What would happen if you discovered that your family was one of the most powerful in human history? What if you were told that the source of the family's power was hidden around the world, in the form of 39 Clues? What if you were given a choice - take a million dollars and walk away...or get the first Clue? If you're Amy and Dan Cahill, you take the Clue - and begin a very dangerous race.

Amy and Dan find themselves in a new global race but this time, everything’s different. Those closest to them might be working for the enemy, and Amy and Dan are forced to ask themselves how far they’re willing to go to save the kidnapped Cahills. How much can you risk when there’s no one to trust?

The Cahill family has a secret. For five hundred years, they have guarded the 39 Clues - thirty-nine ingredients in a serum that transforms whomever takes it into the most powerful person on earth. If the serum got into the wrong hands, the disaster would rock the world. So certain Cahills have always made it their mission to keep the serum safe, buried, locked away. Until now. Thirteen-year-old Dan Cahill and his older sister, Amy, are the latest guardians of the Clues. They think they've done everything right, but a tiny mistake leads to catastrophe.

At only seventeen years old, Ian Kabra is head of the Cahills, the most powerful family in the world. He has presidents on speed dial, generals at his beck and call. Ian knows he's an ideal leader and the only man for the job. There's just one small problem: He's already messed up big time. A Cahill from the past calling himself the Outcast has risen to challenge Ian with an impossible test. The Outcast has re-created four of history's greatest disasters and dared Ian to stop him.

The former God Apollo is having a pretty rough time of it. Well, for one thing, he's called Lester. But being an awkward mortal teenager is the least of his worries. Though he and his friends (some of them) have emerged from the Burning Maze, they still have a triumvirate to defeat, oracles to rescue and prophecies to decipher so that the world may be saved, and Lester can become Apollo once again. But right now, Caligula is sailing to San Francisco to deal with Camp Jupiter personally, and they have to get their first. Or risk its destruction.....

The god Apollo, cast down to earth and trapped in the form of a gawky teenage boy as punishment, must set off on the second of his harrowing (and hilarious) trials. He and his companions seek the ancient oracles - restoring them is the only way for Apollo to reclaim his place on Mount Olympus - but this is easier said than done. Somewhere in the American Midwest is a haunted cave that may hold answers for Apollo in his quest to become a god again...if it doesn't kill him or drive him insane first.

Myles is impeccably neat, has an IQ of 170 and 3-D prints a fresh suit every day - just like his older brother, Artemis Fowl. A week after their 11th birthday the twins are left in the care of house security system NANNI for a single night. In that time, they befriend a troll on the run from a nefarious nobleman and an interrogating nun, both of whom need the magical creature for their own gain....

Look, I didn't want to be a half-blood. I never asked to be the son of a Greek God. I was just a normal kid, going to school, playing basketball, skateboarding. The usual.

Now I spend my time fighting with swords, battling monsters with my friends, and generally trying to stay alive. This is the one where Zeus, God of the Sky, thinks I've stolen his lightning bolt - and making Zeus angry is a very bad idea.
