Unexpected Minion

Either way, a tiny sarcastic ball of kitty fur.

When eighteen-year-old witch Serenity casts a spell, bad things happen. When she takes her test to join the coven, she knows she'll fail in spectacular fashion in front of the entire coven. Then, after a cult burns her family's home to the ground, nearly killing her baby brothers, she discovers she isn't who she thought she was. Her mother said her father was dead. She lied.
Serenity's father is alive ... and he's a demon.

Knowing the hunters who almost killed her brothers won't rest until both she and her father are destroyed, her father gifts her a demonic minion to help her tame her wild magic. But minions are unruly creatures. Can she learn to control the demonic kitten and her magic in time to save her father's life and her own?
