I think this book is good in giving a picture of what is going to happen in the final book Percy Jackson and the Olympians: the Last Olympian. I think it is very good, as are all the other books, at following up with what Rick Riordan started in the first book, The Lightning Thief. And what did he start up in The Lightning Thief??? Percy getting in trouble with the Olympus gods and saving the world!!!!!
