In a fun twist on this genre, Jesse Q. Sutanto's young adult thriller "The Obsession" ($7) doesn't leave the question of who did it shrouded in mystery — in fact, this riveting read is told from the perspective of the murderer.

Now, it's up to Delilah to take control of the narrative and get Logan off her back for good.
