I started studying greek mythology after I read the four Percy Jackson and the Olympians books by Rick Riordan. They are great books. Buy a copy of each one. We will name them by # they are in the series: The Lightning Thief, The Sea of Monsters, The Titans Curse,and The Battle of the Labyrinth. Those are the only books out right now the fith and mabye final book is called "The Last Olympian." I cant wait until it comes out. I'll tell you when it comes out. They're making a movie about those books. It hits theaters sometime in October. So keep an eye out for those books and movie.
Also, I would like to mention my book, ' The Island of the Minotaur ', by Rick Oberman.I got all the info for ' Creation of the Gods ' from there. It was very helpful.
