This book is very suspenseful and likes to give you so many cliffhangers you would be so surprised what happened next.

The movie is really the same to the book, so it's what you said for 2 things.... :)

There is a movie version, very similar to the book version.... Some things might not've been revealed to us in the movie.

me too.. I got suspicious when Percy said " I know you".. The book timeline is the same as The Lost Hero and the early part of The Mark of Athena.
