This book is great in theory. I wish the biographies had been with the letters because I flipped back and forth to see who was writing that specific letter. Some letters were really insightful. Some were quick and obligatory. I loved JK Rowling's and Jodi Piccolt's letters. They were thoughtful, humorous, and I could see a 16 year old understanding them. Jim Belushi's was heartfelt as well and gave us insight to his 16 year old self. Others were just meh. That was very disappointing ot me.
