In this sequel to The Lightning Thief, Percy Jackson, demi-god son of Poseidon is back. With his friends, including a daughter of Athena and a teenage Cyclops, he must once again go on a perilous journey to defy the gods and save the day. Should they fail, their only safe refuge will be gone forever. This is a thoroughly-enjoyable continuation of Percy’s story, and proof that Riordan is on a roll with the Percy Jackson series.
