Putting on the Witch (Retired Witches Mysteries) by Joyce Lavene and Jim Lavene
This is the third book in the series, but the first one that I have read. I really enjoyed the writing and the characters were enjoyable. I enjoyed their enthusiasm is getting a chance to go to the ball (who doesn't like dressing up). and of course a murder occurs. The coven works together to find out who is responsible and I enjoyed seeing the way they thought things out to solve the mystery. An enjoyable book that I would highly recommend.
