Percy survived his first year at Camp Half-Blood, and made many friends along the way, even if one tried to kill him. Now he gets to brave the realities of undersea politics, handle a custody dispute, and deal with land school all at the same time. Camp's barriers weakening after the winter solstice and a new activities director being pulled in did not make his summer session any calmer. Why can't he just have one normal year on land? Makes him wish for Kym's storm-making lessons. SEQUEL TO: ATLOP: Trial by Fire (must read that first to have any idea what's going on)
