Another strong book in the Percy Jackson series. The characters are growing up, and the enemy is growing stronger. The labyrinth was fascinating, especially the locations where they popped up.
My only issues were faults of my own--there were a few things I had forgotten about in between books that caused momentary confusion. And as is always the case with this book, I really need some sort of myth reference book by my side as I read. One of these days, I'll reread all of them with a myth book--but for now, I'll just enjoy the ride!
