I'm on book 4 of the Percy Jackson series and it's awesome! You should totes read it! It was the school craze, but even though it's out of fashion I still love it! And I love books! Don't tell Roonies!
Rain Reign is about a girl named Rose who is obsessed with homophones, her own name has a homophone: rows. She has a dog named Rain, which has 2 homophones: rein and reign. When Rose's father lets Rain out during a storm, Rose must find her dog before some else does.
