Kathryn

Kathryn is a supporting character in Monster Blood. She is the great-aunt of Evan Ross.

History
For over twenty years, Kathryn has been the slave of Sarabeth, a witch disguised as her pet black cat. Sarabeth took away Kathryn's hearing and refused to let her learn sign language to make her more dependent on Sarabeth.

Kathryn's family and loved ones thought that she was just eccentric and mean, but Kathryn was hiding the secret of Sarabeth from everyone. When her great-nephew, Evan Ross, comes to stay with her for a few weeks, Sarabeth gets angry and forces Kathryn to curse Evan's new toy: a can of Monster Blood. Kathryn rebels against Sarabeth quietly by whispering to Evan to be careful after she curses the Monster Blood.

Kathryn's cursing of the Monster Blood, spell books in the room she set up for Evan, and a bone she wears around her neck leads Evan to believe that Kathryn is a witch. He assumes Kathryn is responsible for trying to harm him with the Monster Blood before the truth about Sarabeth is revealed.

After Sarabeth is consumed by the Monster Blood and disappears, Kathryn regains her hearing.

Physical appearance
Kathryn is described as a large woman with "startling" black hair. Evan says that Kathryn's hair makes her look younger than her age of eighty.
