Cassandra Cain can't speak, read, or write. And that
only makes her more powerful. Trained to use all her senses in order to enhance
her fighting capabilities, Cassandra Cain pushes herself to every limit
imaginable. When Vesper Fairchild is murdered, Batgirl, Nightwing, and their
allies search for every possible clue that could lead to her killer. The whole
Bat-family is on edge and prepared for anything, unsure who to trust and who to
suspect.
