I LOVE this series of books, currently there are 4 books out.
The Lightning Theif
The Sea of Monsters
The Titans Curse
The Battle In The Labrythn

These are such good books! The book have alot of greek mythology in but you can read in them without knowing the myth stuff. Its a very good action adventure series that has its funny side, I recommend these books to ANYONE who likes to read because they are not hard reads.
I wondered if anyone else liked these books XD
