This one had me hooked from the awesome opening scene (the prologue). While there are some typical characters - like the outcast, poor smart girl who ends up with the rich, hot jock - the authors do a nice job adding some unconventional twists. The Latina main character is a nice start, and lots of family issues with bankruptcy, cancer, Aspergers and other skeletons in the closet keep them interesting. To be honest, I was worried that this would become "Just another Teen Party book" but I was surprised by the adventures and twists and turns it took me on. A fun read for older teens.
