Just wanted to let you guys know when each of my books were started, so you understand why some are so much better than others.
"In A Gloomy Tower" was started when I was 11. I have run out of ideas for it, but if I suddenly get inspiration I'll work on it some more.
"A Cave In The Sand" was made when I was 11-12 years old. It is the only book I've ever finished (although it is a short story). It was created for my cousin as a birthday present. 
"18 Years Of Sorrow" was started when I was 13 and the last couple chapters I did when I was 16, but I'm currently working on it whenever I get the chance. It has a lot of potential, I just need enough time to reach it.
"It Started With A Crush" is my longest book by far. I've been working on it since I was 14 (so about three years), and I think at the moment it's my favorite.
"Memory" Is my newest, started right after my 17th birthday, and I'm working on it whenever I can. It would have to be my second favorite, but I can't wait to see how it turns out!
