Mother May I

Love will launch the mother of all battles.
Book 4 in The Knight Games Series
Grateful Knight is one stressed out witch. Not only has she failed to restore her caretaker, Rick, from an evil witch's mind-control spell, but the loss he endured extends well beyond his memory. To make matters worse, compensating for his absence could cost her the job she loves and the strength she needs.
When a new supernatural threat leaves Grateful for dead, a vampire ally saves her life but at a price. Her assailant's calling card makes it clear she's marked for death, possibly by her goddess mother. With the help of her half-sister Polina, can Grateful gain the power she needs to win Rick back and beat the goddess at her own game?
