Eating up the Evidence — E.N. Crane

A night Cynthia "Cyn" Sharp doesn't remember and a building burned to the ground.

Celebrating Cyn's new sister-in-law should have been unforgettable... but after her mom spiked the brownies, no one remembers quite what happened, least of all Cyn. Which is very important when she's arrested for Arson. As small fires spring up all over town, and no one is quite sure why, Cyn and Winnie will work to find the arsonist without having to remember too much about the night in question.
