Hmmm...this is hard! In my relatively short lifetime I must have read thousands of books!
A few I do like include:
1. The Time Traveler's Wife - Audrey Niffenegger
2. The Twilight Saga - particularly Eclipse and Breaking Dawn - Stephenie Meyer
3. The Lovely Bones by Alice Sebold
4. Library of the Dead and Book of Souls by Glenn Cooper - compelling reading!
5. All books by Patricia Cornwell, Kathy Reichs and Karin Slaughter
6. Before I Fall - Lauren Oliver - had me in tears a couple of times
7. Before I Die - Jenny Downham - I was in floods of tears with this one (and I really am not a cry at books person!)
8. Thirteen Reasons Why - Jay Asher
9. The Boy in the Striped Pyjamas - John Boyne
10. The Curious Incident of the Dog in the Night-Time - Mark Haddon
