Zeus and the Thunderbolt of Doom (Heroes in Training, Bk. 1)

Ten-year-old Zeus is mystified (and super-annoyed) by the fact that he keeps getting hit by lightening. Every. Single. Year. He also longs for adventure, as he has never been far from the cave where he grew up. Zeus gets his wish - and a lot more than he bargained for - when he is kidnapped by dangerous, giant Titans In self-defense, Zeus grabs the first thing he sees - an actual thunderbolt he pulls from a stone that is covered in mysterious markings. Zeus is the only one who can decipher the markings, and sets off on a quest to rescue his fellow Olympians from the evil Cronus. Armed with his trusty thunderbolt (named Bolt, of course), Zeus is on an adventure of a lifetime - and a journey to fulfill his destiny as King of the Gods.
