The book series, Percy Jackson and the Olympians, is about a boy named Percy who finds out in his thirteenth year of life that he's a half-blood, a child of a mortal and a god. Percy just so happens to be the son of Poseidon, Roman god of water, meaning he has control over the depths as well. Sent to Camp Half-Blood, a summer camp for children like himself, he makes new friends like Annabeth daughter of Athena, and finds some old faces, like his buddy, Grover, who's really a satyr in disguise. During his stays, he is sent on quests with his friends and faces villains while doing so. But heroism comes at a price: Percy has dealt with pain, betrayal, and even death while trying to stop, or at least pause, the ever rising forces of his grandfather, Kronos, and the reawakening of the Titan Lord himself! What I enjoy about these books is their humor, the way they make the mythical characters of long ago apart of our lifestyle today (Imagine: Medusa running a garden gnome emporium!), and how Percy gets used to being not quite a normal kid (You mean a boy who can control three-fourths of Earth's surface ISN'T normal?). Rick Riordan (The author) has created, what I think, a very easy to understand, past mixing with present type of book that has been enjoyed by, I believe, millions of readers and will be enjoyed by many more in the days, weeks, months, and years to come.
