It was a hard one to decide this year but drumroll please...
My favorite book of 2013 was:
Memoirs of an Imaginary Friend by Matthew Dicks
This book really stuck with me. It managed to be both sweet and thrilling (an odd combo!), with a truly unique main character and premise. It made me cry which is hard to do, and even though it's been months, I still think about this book from time to time. I really loved the relationship between Budo and Max, I loved the awesome teacher, I loved the other imaginary friends, so it was mostly the characters that made this book for me. But the quandary Budo found himself in and how he solved it was creative and perplexing, but the solution was believable and logical.
I said it in my review and I'll say it again. Everyone should read this book.
