Battle of the Labyrinth (Percy Jackson, Book 4)

Battle of the Labyrinth (Percy Jackson, Book 4) by Rick Riordan
Once again, this is an enjoyable book as Percy heads towards sixteen (he is 15) and the fateful prophecy. I was a bit irked by the references to vegan/vegetarians in this book after the teens visit a cattle ranch of the gods.

Percy Jackson isn’t expecting freshman orientation to be any fun. But when a mysterious mortal acquaintance appears on campus, followed by demon cheerleaders, things quickly move from bad to worse. In this latest installment of the blockbuster series, time is running out as war between the Olympians and the evil Titan lord Kronos draws near. Even the safe haven of Camp Half-Blood grows more vulnerable by the minute as Kronos’s army prepares to invade its once impenetrable borders. To stop the invasion, Percy and his demigod friends must set out on a quest through the Labyrinth–a sprawling underground world with stunning surprises at every turn. Full of humor and heart-pounding action, this latest audiobook promises to be their most thrilling adventure yet. (Amazon comment)
