The Sea of Monsters by Rick Riordan is the second book in the Percy Jackson and the Olympians series. In this book, Percy and Annabeth, along with the help of Tyson, a cyclops, travel to the Sea of Monsters to rescue Grover (their satyr friend). They also need to find the Golden Fleece, a cure for Thalia’s Tree, which was poisoned. The tree protects Camp Half-Blood and if the three friends don’t find the fleece and Grover, it might be too late.
