33 Books About Time Travel, Parallel Worlds & Alternate Universes

Books about time travel, and novels involving parallel worlds and alternate universes can offer both wonderful fictional escapes and mentally stimulating reading. Whether an avid fiction time traveler or just dipping your toe in the time pond, you will find a great new read in this time travel books list.

Time Travel Book Terminology

The beauty of books about time travel is that each author writes their own rule set. However, there are some underlying norms in this popular science fiction sub-genre.

Characters being transported to the past or future either by mechanical or scientific means (as in HG Well’s 1895 novel, The Time Machine) or other other fantastical means, such as ghostly intentional magic (Charles Dickens’ A Christmas Carol, 1843) or less intentional/controllable time slips (Penelope Lively’s 1976 children’s classic, A Stitch in Time).

A plot device where characters experience a certain span of time repeatedly, either by their own choosing or as some form of lesson or punishment.

Fictional worlds with obvious similarities (or parallels) to our own but also notable differences; like copies of the original where events either have already or will in the future follow a different course. These worlds typically operate on a timeline in parallel with our own. The idea, flowing from quantum physics, is that every time a choice is made new parallel universes are created where each possibility actually happens.

The terms ‘alternate’ and ‘parallel’ worlds/universes are often used interchangeably. However, for the purposes of this best time travel books list we will consider ‘alternate universes’ ones with distinct fantastical elements (e.g. Lewis Caroll’s 1865 Alice in Wonderland), or at least ones where there are more differences than similarities to our own.

Time Travel Book Themes

The time travel and parallel universe story frameworks are most often used to explore what-if scenarios (as in the iconic Sliding Doors movie), the concepts of fate, karma, causation and nature versus nurture, along with the related dramatic notions of hindsight and regret. There’s nothing quite like being transported to a parallel fictional world to hammer home all the things that could go wrong for a character, and how good their current ‘real world’ situation actually is!

Time loops offer protagonists opportunities to learn from past mistakes. Alternate universes can shine a spotlight on closed, narrow-minded thinking or behaviour, force characters to walk-a-day in another’s shoes, and/or reconsider detrimental ‘grass is greener’ attitudes. Some time travel books are more meta in the sense that they overtly interrogate the time travel rule set.

Iconic Romantic Time Travel Books

Time Traveller book - Audrey Niffenegger

The Time Traveler’s Wife by Audrey Niffenegger

One of the best time travel books of all time, this iconic love story is the title that sparked my enduring attraction attraction to the genre. The Time Traveler’s Wife lead characters Henry and Clare are strikingly real despite the very unreal situations they find themselves in. Their struggle to lead normal lives in the face of a force they can neither prevent nor control is intensely moving. A cleverly told heartwarmer and valuable reminder of the fragility of our lives and the virtues of living in the moment. (Full Review | Amazon | Libro.fm)

Best books about time travel - To Say Nothing of the Dog

To Say Nothing of the Dog by Connie Willis

To Say Nothing of the Dog, a hapless yet charming romp through time and space is one of the most intelligent and enjoyable audiobooks I have ever listened to. Protagonist Ned Henry is your quintessential good-hearted underdog finding his way through a maze of Victorian manners, literary debate, domineering women and animal wrangling with absolutely hilarious consequences. And, Connie Willis’ prose oozes intelligence, wit and class. (Full Review | Amazon | Libro.fm

Best time travel romance - Outlander

Outlander by Diana Gabaldon

Outlander, the chunky, at times raunchy, page-turner that began one of the most epic time travel book series’ and decades later its cinematic TV adaptation has gained countless new fans. This story about time travel plays off the Scottish highland pagan folklore (with a time-slip) and a history scarred by warfare. Strong-willed and highly capable, Claire Randall finds herself torn between duty to her conservative British husband (1945) and the passion and impulsiveness of a Scots warrior she initially clashes with in 1743.

Parallel Universe Romance Novels

Parallel universe stories - The Impossible Us

The Impossible Us (aka Impossible) by Sarah Lotz

This epistolatory, genre-bending novel shimmers with romantic tension, and must rank as one of the best books with parallel universes I have read. The blistering rapid-fire dialogue, and authentically raw and messy pulsating hearts of Lotz’s lead characters Nick and Bee had me glued to its pages.  It is about love in all its mysterious and wonderful forms – the romantic (big tick), but also the love between friends, parents and children, cranky neighbours and animals… even love for a cause and ultimately, for ourselves.(Full Review | Amazon | Libro.fm)

Parallel worlds books - This Is How You Lose the Time War

This is How You Lose the Time War by Amal El Mohtar & Max Gladstone

The most ‘poetic’ science fiction I have read. In regards to the time-travelling construct, the nature of the different parallel worlds, warring parties and even the lead characters themselves, readers are constantly being challenged to break out of stereotypical thought patterns and open our minds to new possibilities. Through the exchange of letters, painstakingly composed and hidden where the other will stumble across them years (even millennia) later, they learn the nature and experiences of the other. (Full Review | Amazon)

The Psychology of Time Travel

The Psychology of Time Travel by Kate Mascarenhas

Time travel has largely been a male-dominated zone, and so The Psychology of Time Travel featuring a highly intelligent and strikingly independent female character set is refreshing to say the least. Refreshing also is its exploration, and in large part normalisation of societal diversity, e.g. romantic, socio-economic, cultural. Mascarenhas has also re-written the time-travel rule book. A very clever and highly original take on time-travel fiction. (Full Review | Amazon | Libro.fm)

Time travel adventure fiction - Here and Now and Then

Here and Now and Then by Mike Chen

I was impressed by the effortless credibility of Mike Chen’s execution of time travel. So many wonderful little details are woven seamlessly into the story fabric — everything from hover cars, food trends and social diversity being the norm. But as impressive as Chen’s deft plotting and world-building is, he never forgets that his characters must remain centre stage. For me, this is a time travel tale a cut above the rest — at times heartrending but ultimately uplifting. A page-turner brimming with heart. (Full Review | Amazon | Libro.fm)

Contemporary Parallel World & Alternate Universe Novels

Best time travel books - The Eyre Affair

The Eyre Affair by Jasper Fforde

The first title in the author’s Thursday Next Literary Detective Series which achieved an almost cult-status amongst booklovers. Why? The wit, wordplay and satire on display. Time travel is common place and it is possible to travel ‘into a book’, in this alternate world where appreciation of literature is high in the social conscience. And of course, its loveably loyal, flawed and feisty heroine named Thursday Next, a SpecOp-27 (Literary Detective Division of Special Operations) with a genetically flawed dodo as a pet. I found this one a delight. Read my The Eyre Affair review >>

Books about alternate realities - A Wrong Turn At The Office of Unmade Lists

A Wrong Turn at the Office of Unmade Lists by Jane Rawson

One of the more literary books about alternate realities I have read. This 2013 meta-fiction combines a Narnia-like storyline with a dystopian climate future, the latter less fanciful by the day. The fictional ‘climate change disaster’ — floods, fire, drought, energy crises – has led to a drastic widening of the socio-economic divide. Good-natured dry humour and entertaining banter of endearingly flawed characters is the means by which Rawson explores deeper themes — loss and bereavement, resilience and survival.

But her quiet existence is shattered when she stumbles across a strange book. A book that tells a tale of secret doors into new worlds, of love, adventure and danger. Each page reveals more impossible truths, and January discovers a story increasingly entwined with her own. Find out more >>

Classic Time Travel Books & Alternative Universe Literature

Graphic Novel A Wrinkle in Time - Hope Larson

A Wrinkle in Time by Madeleine L’Engle

In this Newberry award-winning classic, three strange figures, Mrs–Who, Whatsit, and Which, send Meg and Charles Wallace, and their friend Calvin O’Keefe, on a mission (via tesseract, a wrinkle in space-time that allows fast travel between distant points) to find their father Mr. Murry, a missing government physicist.

I reviewed the graphic novel by Hope Larson.

Flatland - A Romance of Many Dimensions by Edwin Abbott

Flatland: A Romance of Many Dimensions by Edwin A Abbott

This classic 1884 satirical novella is ostensibly an exploration of dimension theory. It describes the journeys of A. Square and his adventures in Spaceland (three dimensions), Lineland (one dimension) and Pointland (no dimensions). A. Square also entertains thoughts of visiting a land of four dimensions — a revolutionary idea for which he is banished from Spaceland. But satirically, it delves into the role of women in Victorian society, rigid class structures, the influence of organised religion, the suppression of individuality and even euthanasia.
