Candlemaker Hazel Wickbury has a secret. She knows when someone is going to die.

Welcome to Crucible, a small town with a storied history. Founded by five prestigious families, Crucible has been tucked away in upstate New York for centuries under the protection of a shield enchantment cast by Jedidiah Glenmyre, Hazel's revered ancestor. The enchanted barrier is meant to protect Crucible from anything bad ever happening to the town. No crime, no awful weather, no natural disasters—a haven from the greater world.

That is, until the heir to a billion-dollar company is found dead in his home. With the help of her uncanny power, known as a "whim," Hazel realizes foul play is involved. But more than being concerned about a murderer running loose and Jedidiah Glenmyre's protection shield deteriorating, Hazel and her aunt Poppy are worried the town's kindhearted art teacher will be charged with the sinister crime.

Hazel and Poppy team up with an internationally acclaimed mystery author visiting Crucible to figure out who had it in for the victim. Their fledgling investigation has them questioning if long-time friends have turned into foes, and whether blood is really thicker than water.

Determined to prove her friend innocent, Hazel is ready to shine a light on the real killer…if they don't snuff her out first.
