The Lovely Reckless by Kami Garcia
Thoughts at a glance: **** (I really liked it) Summary: Frankie Devereaux wishes she could forget witnessing her boyfriend's murder - except that due to PTSD, she can't remember enough of it to help catch the killer. In the months since, Frankie has seen her life slide downhill - once a Stanford-bound straight-A student at a wealthy private school, Frankie lands herself in some hot water which leads to her getting sent to live with her father on the "bad" side of town. At her new public school, good girl Frankie is immediately drawn to bad boy Marco Leone, who participates in some very illegal activities. Their chemistry is undeniable, but so are their differences, especially considering that Frankie's father is an undercover cop. And when he finds a lead that connects to Marco, things get really complicated.
