This is the second novel in the Percy Jackson and the Olympians series and was just as exciting and as quick a read as the first book. With the beginning of this book the reader finds Grover on his search to find the legendary Pan, god of the wild, and Percy trying to survive yet another school year in the mortal world. Giants attack Percy and he discovers that his friend over this past year is a cyclops named Tyson, whom we later find out is his half brother when Poseidon claims him similar to the way he claimed Percy.
As they make their way to camp, they find out how much things have changed and how dangerous the world has become for half-bloods. Luke, a son of Hermes, has poisoned the sacred pine tree and the camp’s protections are slowly fading. Meanwhile, a full grown, incredibly dangerous cyclops holds Grover captive, and also has in his possession the legendary Golden Fleece. We discover that Grover bound himself to Percy so that if he dies so does Percy creating a greater sense of urgency.
