Sorcerer - Coven, #5

Mind your secrets. Samantha and Steven's wedding day has finally arrived! As the bride and groom and their wedding party prepare for the big day, Talia, the officiant of the wedding who is a witch herself, collapses and is taken to the hospital. Seeing her sister begin to panic that her wedding is falling apart, Kathy uses magic to find another officiant-but her spell summons Augustus, a sorcerer who has his own agenda.
Unbeknownst to Kathy, she wasn't alone when she cast the spell, which gives Steven's mother the ammunition she's been looking for to put a stop to the wedding. While the sisters are preoccupied with preparing for the big day, a news reporter shows up and catches the use of magic on camera. With the wedding day effectively ruined, Samantha and Kathy must figure out how to put their secret back in the bottle.
To make matters worse, Augustus disappears and all the signs point to Talia's collapse being connected to his arrival. In order to stop Augustus and keep their secret, Samantha and Kathy must rely on help from others, which seems impossible to do when their home is surrounded by news reporters. Sorcerer is the fifth book in the Coven series, which serves as a prequel series to the Under the Moon series.
