And even though he received a minimum level of training, he has never been in the field… Until now.

Ainsley Hanes has a really big secret she has carried with her as she has moved around the last three years. She finds herself in trouble, though she doesn’t realize how much trouble she really is in, nor does she realize she needs help.
