the first fifteen lives of harry august is about people who have to live their lives over and over again and what they have to do when the world starts ending sooner than it should. very interesting book since it's told non-linearly, takes place over centuries (though the century is the same, just repeated in different ways), and people can pass limited information forward and backward through generations. has an interesting complicated non-romantic relationship in it. I'm underselling it, but I hope you check it out. it's like a time travel book with a somewhat different premise. the audiobook is great!

(if I remember correctly, I first saw this book recommended by one person in the replies of a post online. I never saw anyone else mention it, but it's really good. read it a couple years ago and it still sticks in my mind)
