Percy Jackson and the Battle of Labyrinth by Rick Riordan

Puffin Books, 2009.
(Age 10+) Percy Jackson is a half-blood, the son of Greek god Poseidon. This makes life quite complicated as he faces daily battles with enemies while trying to continue his studies at Camp Half-Blood. His arch-enemy may have discovered a secret passage through the Labyrinth which would allow him access to the camp. This means none of the half-bloods are safe. So Percy joins his friend Annabeth on her quest underground, where they face untold horrors and battles to save their existence. They must also discover the truth about the lost god Pan to help their satyr friend Grover prove he is not crazy.
With a feeling of Harry Potter meets Buffy the Vampire Slayer, Percy Jackson and the Battle of the Labyrinth, as with the other Percy Jackson books, provides an entertaining yet dramatic journey.
