Bayport High operates like any other high school—jocks at the top, outsiders at the bottom, and everyone else in between. Enter Toby Klein, a sophomore computer hacker who doesn't play well with others. She has zero school spirit, a black belt in karate, and what her guidance counselor calls an attitude problem. She's the last person you'd expect to be invited to join the varsity cheerleading squad. But things are different at Bayport. Bayport's varsity cheer squad is made up of the hottest of the hot. But this A-list is dangerous in more ways than one. The Squad is actually a cover for the most highly trained group of underage government operatives the United States has ever assembled. Athletically, they're unmatchable, though they make it all look easy on the field. Mentally, they're exceptional—but with one flash of their gorgeous smiles, you'll completely forget that. Socially, they're gifted, so they can command and manipulate any situation. And above all, they have the perfect cover, because, beyond herkies and highlights, no one expects anything from a cheerleader. Toby Klein might not seem like the most likely recruit, but she's never been one to turn down a challenge. If she can handle the makeover, Bayport Hight may just have found its newest cheerleader. Pretty, popular, armed, and extremely dangerous—meet THE SQUAD.

Saying Toby Klein is an unlikely cheerleader is like saying Paris Hilton might be into guys—understatement of the year. But the varsity squad at Bayport High gives new meaning to the phrase All-American, and Toby's double life as a varsity cheerleader and a government operative means balancing protocol, pep rallies, computer hacking, and handsprings. Now something's about to go down in Bayport, and the Big Guys Upstairs need to know what. The Squad is on the case, but it looks like this mission could put the "l" in lethal. And if the spy business doesn't kill Toby, it's starting to look like Brooke, the team's captain, might. The nominations are in for homecoming court, and rumor has it that Toby is the unlikely front-runner for queen. Terrorist threat? Bloody mission gone wrong? Demented squad captain? Bring it on.
