Love this one, and the series just keeps getting better & better. This is always a pleasant outcome, because sometimes the first book in the series is the best, but Riordan comes through with every word. I picked up the first book of the series purely because I know Riordan's mystery series & liked them very much. Much to my surprise, I loved this juvenile series as much if not more.
Wonderful imagination all the way through & a very clever folding of ancient mythology into the present day world. In this book, Percy Jackson and his famous pen/sword, Riptide, once again try to go back to school. Let's just say the cheerleaders are not quite what they seem. Chance encounters, old & new friends coming together, all blend to create yet another fantastic adventure. In this one, Annabelle takes the lead through the Labyrinth, and they encounter the master of the labyrinth, as well as many creatures who abide in the Labyrinth. Saying more would ruin the story for others, but suffice it to say that the great hearts, great love, and great anger behind the characters in the book turn it into a most compelling adventure story. Well worth reading for anyone who loves fantasy/SF and for anyone who loves good juvenile literature.
