Book One of the Percy Jackson & The Olympians series is The Lightning Thief
I saw the previews for this movie and decided to pick up the book and see what it was all about. I thoroughly enjoyed the book. I read it a few weeks ago, somehow missed putting it in the blog before reading several other books and then the next in the series (while I waited patiently for the second book to be available at the library).
Book Two of the Percy Jackson & The Olympians series is The Sea of Monsters
Finished this one off last night. Very pleasant read. This is a kids series (8, 9, 10 ages I would guess) but just as enjoyable for adults. I started it right around dinner time two days ago and read the last couple of chapters when I was putting my daughter to bed last night. It is not stop action and never leaves you bored with the story line. Percy Jackson and his friends, new and old, are great characters and the story is awesome. Started the next in the series last night too!
