The Festival of the Moon (Girls Wearing Black

Still reeling from the events of the Homecoming Masquerade, Nicky Bloom must prepare for the second event of the Coronation contest: The Festival of the Moon.
A week-long celebration of the immortals and the girls vying to become one, the Festival of the Moon begins with a wild party in the woods and ends with a date auction, where all the boys of the Thorndike senior class bid for the right to wine and dine one of the girls wearing black.
With help from Jill Wentworth and the rest of the Network, Nicky dives headfirst into the world of lust, gossip, and intrigue that is Thorndike Academy. And as she and the other girls wearing black struggle for position, Nicky must keep her true identity a secret, not only from the other students at school, but from the vampire who is watching her every move.
