Here's the description from the book flap:
Bored out of her mind during a summer with her police detective father in Las Vegas, Jessica (aka "Jex") Malone starts doing what she does best--snooping. When she meets three new friends who share her passion for crime, from the geek to the fashionista, suddenly, the stifling desert days don't seem so long.
Her dad is never around, just like when her parents were married. But Jex's crew, the Drew-Ids, take the pledge of eternal secrecy and then get down to the good stuff--digging through the cold-case files in Dad's home office.
One of them, the thirteen-year-old case of Patty Matthews, is still a mystery. Finding Patty, who vanished into thin air, became such an obsession for Jex's father that it destroyed the Malones' marriage. So not only is this a big deal, it's personal.
Jex is determined to find out what really happened, and her excitement is contagious. Soon her friends are all on board and so is the missing girl's brother, the hunky Cooper Matthews.
But as they dig up more and more troubling information--more than the cops ever did--they also get the clear message that someone out there wants to prevent the truth from coming out. That somebody is also prepared to do anything, absolutely anything, to prevent it.
Jex isn't afraid; after all, she's a cop's daughter. But maybe she should be.
I really liked Jex Malone. Once I got into the story, which didn't take long, I couldn't stop reading. I kept wanting to peek ahead, but I resisted the temptation. I'm glad I did, because the unfolding of the story is so enjoyable to read.Laced with humor, toughness, and real CSI investigation techniques, Jex Malone could be the Nancy Drew for a new generation--but with a chilling twist. These wannabe detectives are on the brink of finding out the fate of poor missing Patty. But will they disappear without a trace, too?
The characters are a bit stereotypical, but I didn't think that detracted from the overall story. The girls, though all different from each other in personality, are realistic teenagers.
I have just one picky thing to point out. The story opens in New Jersey, where Jex lives with her mother. On the very first page of the book, Jex is "sitting on this hard wooden bench in the Arlington County Courthouse." New Jersey has 21 counties, and Arlington is not one of them. I can overlook the fact that Spring Heights doesn't exist, but naming a real county would be easy. However, as I said, this is a picky little thing that probably anyone from outside New Jersey wouldn't even notice.
Jex Malone is a family-friendly book: no profanity or adult situations. Boys and men would probably not care for the girl-centric story, but I would recommend it for young women and even adult women who like mysteries.
