I've just finished "The First Fifteen Lives of Harry August" by Claire North. I loved this book, it's been ages since I found a book I couldn't put down. Would strongly recommend it.

It's kind of a time travel book. Best comparison would be the movies Groundhog Day or Edge of Tomorrow -- but with the character living his whole lifetime multiple times rather than a day or two. She's created a very interesting and mind stretching universe that has made me think about life and death and legacy. If you're looking for a scifi book to read give this one a chance.
