The Squad: Perfect Cover and The Squad: Killer Spirit by Jennifer Lynn Barnes are the first two books in a series.
Toby Klein was just your average high school hacker-loner-who-is-also-a-black-belt-in-karate, until she is recruited to join her school's varsity cheerleading squad-- something she would never do in a million years. Until she finds out that the squad is actually a cover for a team of highly trained government agents. Suddenly, Toby goes from being the aforementioned loner-hacker who occasionally beats up football players to being one of the most popular girls in school. She is quickly pulled into a web of intrigue, danger, and body glitter. Lots of body glitter.
Okay, so, yes, I do realize that this book is about cheerleader secret agents. But that fact notwithstanding, these are fun, enjoyable books. It helps that the main character is very anti-cheerleader, despite the fact that she is one. Also on the plus side, the main character is actually smart, something I would never have guessed by looking at the covers of the books. (I mean, cheerleader silouhettes? Really?) To be honest, I picked up the first one because I thought it would be amusing (unintentionally). I was suprised to find thatI actually enjoyed it (and then read the second one, of course). These are great light reads-- they're clever, there's action, and there's, um, pep rallies. Yeah. And best of all? They're actually written well. (And they're paperbacks, so they're cheap.) So if you've boon looking for something fun to read that you don't have to think about too hard, I've found it for you. You can thank me later.
I give these books 3.5 daggers each.
