I loved this one!! Best book so far in the series! 
 Minor spoilers! 
 So Percy and the gang travel through the Labyrinth to find the architect himself before Luke and the bad guys do.Like wants to use the maze to have an entrance into Camp Half Blood to destroy everyone.Lots of things go down... 
 I enjoyed it from beginning to end. Parts I like- the scorpions chase,Nico and the Happy Meals,the ranch and the animals and the last 150 pages! Smoking hot!I don't want to give anything away but Wow! And Nick is cool I wished we could see more of him to.
