Books like How Not to Die Alone by Richard Roper

Between life and death there is a library, and within that library, the shelves go on forever. Every book provides a chance to try another life you could have lived. To see how things would be if you had made other choices . . . Would you have done anything different, if you had the chance to undo your regrets?” A dazzling novel about all the choices that go into a life well lived, from the internationally bestselling author of Reasons to Stay Alive and How To Stop Time. Somewhere out beyond the edge of the universe there is a library that contains an infinite number of books, each one the story of another reality. One tells the story of your life as it is, along with another book for the other life you could have lived if you had made a different choice at any point in your life. While we all wonder how our lives might have been, what if you had the chance to go to the library and see for yourself? Would any of these other lives truly be better? In The Midnight Library, Matt Haig’s enchanting new novel, Nora Seed finds herself faced with this decision. Faced with the possibility of changing her life for a new one, following a different career, undoing old breakups, realizing her dreams of becoming a glaciologist; she must search within herself as she travels through the Midnight Library to decide what is truly fulfilling in life, and what makes it worth living in the first place.

THE ART OF LOVE IS NEVER A SCIENCE MEET DON TILLMAN, a brilliant yet socially challenged professor of genetics, who’s decided it’s time he found a wife. And so, in the orderly, evidence-based manner with which Don approaches all things, he designs the Wife Project to find his perfect partner: a sixteen-page, scientifically valid survey to filter out the drinkers, the smokers, the late arrivers. Rosie Jarman is all these things. She also is strangely beguiling, fiery, and intelligent. And while Don quickly disqualifies her as a candidate for the Wife Project, as a DNA expert Don is particularly suited to help Rosie on her own quest: identifying her biological father. When an unlikely relationship develops as they collaborate on the Father Project, Don is forced to confront the spontaneous whirlwind that is Rosie—and the realization that, despite your best scientific efforts, you don’t find love, it finds you. Arrestingly endearing and entirely unconventional, Graeme Simsion’s distinctive debut will resonate with anyone who has ever tenaciously gone after life or love in the face of great challenges. The Rosie Project is a rare find: a book that restores our optimism in the power of human connection.

Receiving an invitation to his ex-boyfriend's wedding, Arthur, a failed novelist on the eve of his fiftieth birthday, embarks on an international journey that finds him falling in love, risking his life, reinventing himself, and making connections with the past.

February the fifteenth is a very special day for me. It is the day I gave birth to my first child. It is also the day my husband left me...I can only assume the two events weren't entirely unrelated. Claire has everything she ever wanted: a husband she adores, a great apartment, a good job. Then, on the day she gives birth to their first baby, James informs her that he's leaving her. Claire is left with a newborn daughter, a broken heart, and a postpartum body that she can hardly bear to look at. She decides to go home to Dublin. And there, sheltered by the love of a quirky family, she gets better. So much so, in fact, that when James slithers back into her life, he's in for a bit of a surprise.
