@roblov3r thank you so much! It really helped! I'm thinking on making a list of ideas on where I want my book to go or maybe just simple ideas for book themes, and I'll let you know if it works out! I'm really going towards the idea of writing about either Rose's life after the Doctor, or How Amy and Rory lived their lives after the weeping angels sent them back. I'm still deciding, but I hope it turns out great!
