Twelve-year-old Ben Ripley leaves his public middle school to attend the CIA's highly secretive Espionage Academy, which everyone is told is an elite science school.

In the third book in the New York Times bestselling Spy School series, Ben gets kicked out of the CIA’s spy school and enrolls with the enemy. During a spy school game of Capture the Flag, twelve-year-old Ben Ripley accidentally shoots a live mortar into the principal’s office—and immediately gets himself expelled. Not long after going back to the boring real world, Ben gets an offer to join evil crime organization SPYDER. And he accepts. Ben can tell he’s a key part of their sinister plan, but he’s not quite sure what the plan is. Can Ben figure out what SPYDER is up to—and get word to the good guys without getting caught—before it’s too late?

As 13-year-old Ben, a student at the CIA's academy for future intelligence agents, prepares to go to spy summer camp, he receives a death threat from the evil organization SPYDER, in this companion novel to "Spy School."

"With SPYDER defeated, Ben Ripley is looking forward to his life getting back to normal, or as normal as possible when you're a superspy in training. For once, everything seems to be right in Ben's world...until someone bombs the CIA conference room next door. To Ben's astonishment, the attacker is none other than Erica Hale, the spy-in-training he respects more than any other. Ben refuses to believe Erica is working for the enemy...even if the rest of the CIA does. His mission: prove Erica is not a double agent working against the US, locate the fabled colonial-era insurgent group that's blackmailing her, figure out what their devious plot is, and thwart it. But this time, Ben finds himself up against opponents he has never encountered before: his own friends. They're not as ready to trust in Erica as he is, and Ben is forced to rely on his own wits and skills more than ever before. How can he succeed when he doesn't even know who he can trust?"--

Ben Ripley enrolls in ski school, where the slopes, and the stakes, get really steep in this bestselling follow-up to the Edgar Award-nominated Spy School, Spy Camp, and Evil Spy School. Thirteen-year-old Ben Ripley is not exactly the best student spy school has ever seen--he keeps flunking Advanced Self Preservation. But outside of class, Ben is pretty great at staying alive. His enemies have kidnapped him, shot at him, locked him in a room with a ticking time bomb, and even tried to blow him up with missiles. And he's survived every time. After all that unexpected success, the CIA has decided to activate Ben for real. The Mission: Become friends with Jessica Shang, the daughter of a suspected Chinese crime boss, and find out all of her father's secrets. Jessica wants to go to ski school in the Rocky Mountains, so a select few spy school students are going skiing too--under cover, of course. Ben might not be able to handle a weapon (or a pair of skis), but he can make friends easy peasy. That is, until his best friend from home drops in on the trip and jeopardizes the entire mission...
