White Rabbit by Caleb Roehrig

A ticking-clock thriller set in Vermont. Rufus has one night to prove that his privileged half-sister didn't kill her boyfriend before the cops get involved. April has clearly been set-up and the drug 'White Rabbit' is Rufus' best lead. With time so short he's unable to turn down any help, even if that help is coming from his ex-boyfriend, Sebastian.
Roehrig brings a noir sensibility to 'White Rabbit' that carries what would have been a sanitized thriller into an entertaining read. That noir sensibility includes some pretty fucked up ideas about relationships, and interacting with people in general. That's part of the genre, even if your world-weary detective is a teen with a bad case of the why-mes.
