Life after Life has a gripping teaser: "what if you could live again and again, until you got it right?" The main character Ursula has an infinite number of lives to spend learning and attempting to save the world. My Name is Memory is about a guy Daniel who falls in love with the same girl Sophia for centuries, except he remembers every detail of his many lives whereas she doesn't. I love a great story, and the fantasy/sci-fi theme around reincarnation makes these books super unique.
Do you know any books that would go oh so well together?
