Peppermint Wintersweet is turning eleven, which means she'll finally be declared a real witch instead of just a fledgling. She can't wait to get her very own wand, broomstick, and familiar—preferably a black cat, please.

There's just one thing standing in her way. Her Witch's Evaluation. Peppermint can't enter official witchhood unless she comes up with a witch-tastic magic display to show the judges. She thinks she's created an amazing potion to showcase, but when the potion goes missing, she has to put down her cauldron and pick up her magnifying glass. It's up to her to sleuth her way to the truth. Can she solve the mystery of her magic potion, or will the spooks get the better of her? Join Peppermint to find out!
