Quinn Kelley leads a normal life in a small, quiet Texas town. She teaches at Sutter High School with her lifelong best friends, Eli, Bess, and Jess. One ordinary Wednesday afternoon, everyone is taken completely by surprise when the unthinkable happens! Quinn is in the middle of teaching a history lesson to her students when a scream pierces the air. Quinn darts out the door only to find distraught students, including her own son, rushing out into the hallway because their teacher dropped dead in front of them!

Leigh Taylor was the sweet, new teacher next door and Quinn's friend, so after overhearing that Leigh's death may not have been from natural causes, Quinn sets out to solve the mystery herself. Soon, Quinn discovers that Leigh held a dangerous secret from her past. The local sheriff, Quinn's older brother, Drew Darby, tries to discourage her from getting involved, until Quinn realizes that a poetry game she played with Leigh holds clues to Leigh's murder and the secret she carried to her grave.

To top off the whole situation, Quinn is suddenly beset with the realization that she may be falling for best friend, Eli Bloom. Can she help solve Leigh's murder and navigate her feelings for Eli before the killer can stop her permanently?
