I would say mine is the Miraculous Journey of Edward Tulane. My teacher read it to the class in third/fourth grade and I fell in love with it. It might be because I loved dolls and stuff like that and related to Abilene. I loved seeing Edward going on all of this adventures and I believed for the longest time that he was like a character in Toy Story. I think my favorite part was when he was with this brother and sister. Although many people don’t like it due to its non-kid friendly topics (abuse, manipulation, death),the book just reminds me a simpler time in my life and when I just started to realize reading was fun.
Harry Potter. It reminds me of family, nostalgia from growing up, waiting for later books at midnight and then reading it as fast as possible, talking about them with friends and family, going to see the new movies in imax, watching the abc family marathons. Going to an HP themed college party. Great great memories, plus the books themselves were good. Especially the sixth one with all the pensieve memories, giving glimpses into characters’ mysterious pasts.
This is the only answer. HP is my childhood.
Makes me nostalgic like no other book.
