@AZARZYGP I don't know a lot of werewolf-based novels or mystery, but here's a list of sci fi novels that I enjoyed: Cinder by Marrisa Meyer, Legend by Marie Lu, The Maze Runner by James Dashner, Divergent by Veronica Roth, The Selection by Kiera Cass (this one is more romance than sci fi though), and Glitch by Heather Something (I don't remember her last name, but I'm sure it'll pop up on Google). These are all for young adult audiences (ages 12-18).
(By teen fic, did you mean realistic fiction for teens or just overall teen books?)
