Percy Jackson wants to save his mom, but he is accused of stealing Zeus’s Master Lightning Bolt. So he has to go on a quest from Camp Half -Blood to the Underworld to receive the bolt. Then he returns the bolt and returns to Camp Half -Blood.
I would recommend this book to people who have read other books by Rick Riordan or who are interested in fantasy books about Greek Gods.
My favorite part was when Grover got his Searcher’s License so now he can go search for Pan, the nature god who went missing eons ago.
