Let me just tell you right now that Rick Riordan (in my opinion) is the best author in the world. My favorite books by him are the Percy Jackson series. This series includes; The Lightining Theif, The sea of monsters, The Titan's curse, The Battle of the Labrinth, and The Last Olympian. All are on DOGO. Percy Jackson lovers, do you want more? Then try the new Heroes of Olympus series! This includes; The Lost Hero, The Son of Neptune, The Mark of Athena, and coming soon, The House of Hades!
This is an amazing book where a girl named Tanya can see faries. She goes to her grandmother's manor because her parents think she needs a vacation. She is sent on an adventure that will end her up in some difficult situations. This is one of my favorite book series of all time.
