Silver Charms by Kate Moseman

All Rose wants is peace, quiet, and some quality time with her lovable foster dog, Braveheart. Unfortunately, a devious elder fire witch has decided it’s time to begin Rose’s training in fire magic—and she won’t take no for an answer.
But even fire spells are no match for family drama: Rose’s sister is in the middle of a divorce, and it’s up to Rose to stop the soon-to-be-ex-husband’s plan to keep the house for himself.
With the help of the Ride-or-Die Witches, a friendly fire-setting cat, and a handsome British chauffeur, Rose must fight for her sister’s home… while uncovering a mysterious new threat to the witches of Sparkle Beach.
They say you can’t fight fire with fire, but she’s got magic to burn.
