Though the Greek and Roman crewmembers of the Argo II have made progress in their many quests, they still seem no closer to defeating the earth mother, Gaea. Her giants have risen - all of them - and they're stronger than ever. They must be stopped before the Feast of Spes, when Gaea plans to have two demigods sacrificed in Athens. She needs their blood - the blood of Olympus - in order to wake.

School may be out for summer, but top-secret training continues for aspiring spy Ben Ripley - and so does the danger. Ben Ripley is a middle schooler whose school is not exactly average - he's spent the last year training to be a top-level spy and dodging all sorts of associated danger. So now that summer's finally here, Ben's ready to have some fun and relax. Except that's not going to happen, because a spy-in-training's work is never done.

When Joe Stoshack holds a baseball card, his hand starts to tingle. And if the card is old enough - like the rare Babe Ruth card his father gives him for his 12th birthday - Joe can travel back in time! One of baseball's greatest mysteries is whether or not the Babe actually called his fifth-inning home run in the 1932 World Series. With Joe's new card, he can solve that mystery once and for all. But when Joe and his father travel back in time, they find more than the answer to a baseball mystery.

Ben Ripley may only be in middle school, but he's already pegged his dream job: CIA or bust. Unfortunately for him, his personality doesn't exactly scream "secret agent". In fact Ben is so awkward, he can barely get to school and back without a mishap. Because of his innate nerdiness, Ben is not surprised when he is recruited for a magnet school with a focus on science - but he's entirely shocked to discover that the school is actually a front for a junior CIA academy.

Oliver Zahn, spitball champion and self-declared rule-wrecker of Brightling Middle School, is not a fan of his new homeroom teacher, Mr. Aidact. The guy is sort of stiff, never cracks a smile, and refers to them as “pupils.” The worst part is he catches Oliver before he can pull any of his signature pranks! It’s time for Oliver and his best friend, Nathan, to show the new teacher who’s boss.
