It’s a new semester at Thorndike, and a time for new beginnings.

For Daciana Samarin, it is a time to take control of the school after a lengthy absence. Eager to inject some excitement into a contest that has one girl far ahead of the others, Daciana rolls out a relic from her past, and invites the girls wearing black to explore its mysteries.

For Jill Wentworth, it is a time to evaluate priorities, and determine if the potential rewards of her assignment at Thorndike are worth the risks. Ever the rationalist, Jill believes Washington has become too hot for the mission to continue. But with a changing of the guard atop the clan, there are new opportunities for the Network to explore, including one that just might keep Jill in town, despite the danger.

For Nicky Bloom, it is a time of discovery. Having learned the truth about her family, and the memories that drew her across the ocean, she is prepared to face the truth about herself, and what she wants most in life. When she was in Italy, she had a chance to kill Sergio Alonzo and she didn’t take it. Now it is time for her find out why.

The fourth and final book of Girls Wearing Black follows the seniors of Thorndike Academy in their final semester, when they will conclude the contest that will see one of them become a vampire, and another the vampire’s first victim.
