Determined to find out why Lucenzo's been sending Starr disturbing visions all summer, she flies to Boston to track down his brother. He is the only one who knows where Lucenzo is being punished for his crimes.

Unfortunately, his brother won't talk because of old grudges. When a close friend of his offers to help Starr, she accidentally crosses him, making an enemy of one of the oldest, most vicious Irish vampires: the Scamalls.
