Sourdough Dead, the final installment of The HSP Mysteries, comes out today! Kayla has her hands full with Halloween coming up, a swimming competition to train for, and, of course, a murder! This time, her boyfriend, restaurateur Jason Banks, is the main suspect and she’ll do anything she can to clear his name. Sugar and Flour are up to their usual antics, and all Kayla’s friends are back, too. I hope you enjoy!
