Alek and Evelyn have teamed up again, as the older siblings of the killer family are coming after her. They blame her for their parents death, and they are determined to take her out. The Furies, however, have other plans.
As they work to survive the deranged older siblings, Alek, Evelyn and the twins work together to stay alive, and try to figure out how to defeat the monsters chasing them.

A fun read. I could not put this one down.
