Dark Avenging Angel — Catherine Cavendish

Don't hurt Jane. You may live to regret it.

Bullied by her abusive father, Jane always felt different. Then the lonely child found a friend in a mysterious dark lady who offers her protection -- a lady she calls her “angel”. But that protection carries a terrible price, one to be paid with the souls of those Jane chooses to suffer a hideous and eternal fate.

When Jane refuses to name another victim, the angel reveals her most terrifying side. Payment must be made in full -- one way or the other.
