The Last Olympian

"Yes, it’s the last book in the first series. It’s a buildup of everything that has happened for the last four books and a major part of this book, about half of it, is a battle, which is incredibly interesting, considering I like battles. It’s a huge battle between the main forces of Kronos against the Camp Half-Blood demigods. They use all ancient Greek weapons—swords, shields, spears, bows and arrows—and it takes place in Manhattan, because Mount Olympus is on top of the Empire State Building (it’s hidden by ‘mist’ to look like sky to mortals). Yes, it’s literally Mount Olympus on top of the Empire State Building. Yes, but Rick Riordan adds lots of details, like Apollo is always making up really bad haiku poems because he visited Japan and Artemis really hates all boys and men."
