Magic Happens — Amy Miles

Just when the Black Hat Sorority thought things might get back to normal, as normal as it can be when you are a coven of witches amongst "plain Jane" college students, Seraphina and her friends discover one of their own has gone missing. When a ransom note is nailed to their front door they know things have gone too far. An unlikely alliance is struck with the Sigma Phi guys and with a fall girl in place to cover their tracks, the Black Hat Sorority goes to war.
