What can I possibly say? It was one of those books - one where the pages couldn't be turned quick enough. The demigods and their Olympian parents are nearing all out war with Kronos, the Titans, other demigods, and traitorous gods. Percy, Annabeth, Grover and their friends are about to make some of the hardest choices of their lives - because after this summer, everything changes.
The book retains the series notable humor while showing how the demigods have changed and grown.
