Brutal Brew (Pet Potions Mystery 3)

A recipe for murder…
It’s time for the Potion Masters Society’s annual Brew-off competition! Libby Slade might be new to the potion-making world and is one laboratory accident away from burning down her house, but she decides to dust off her cauldron for the competition.
Potionists from across the state gather, but it’s not the friendly rivalry Libby had been expecting.
When one of the judges dies after testing Marge’s potion, Libby must figure out who the killer is to clear the apothecary’s name.
She uses her sleuthing skills, potions, and a heavy dose of snark to solve this mystery with more twists and turns than ingredients in a potion recipe.
