The Lost Hero last night, and boy oh boy is that some good reading. In case you have been living under a rock, the story takes place after the events in Riordan's series Percy Jackson and the Olympians. The Lost Hero follows 3 demigods that are new to the Camp Half-blood world, Jason, Piper and Leo. The trio are given a quest to free the goddess Hera who has been captured by Gaea, the Greek goddess of the Earth.
This is the first book in the new Camp Half-blood series, The Heroes of Olympus. If the first book is any indication, the series should be just as much fun as the original. I did find myself missing the original characters, but Jason, Piper and especially Leo are good on their own. I mean, Leo makes a giant metal flying dragon, what else could you ask for?
