Ride It Cowgirl - The Training of Cassie, #4

Cassie learns all locations are fair game as far as Frank is concerned when a training session is involved. The more nerve-wracking, the more he likes it. Cassie's stubbornness rears its head, and she refuses to let him win. She endures a lot, but is her endurance enough? Frank is forced to confront his demon lying dormant just below the surface. Cassie has awakened the monster, and it is taking everything Frank has to combat it.
Does Frank succeed or does he relent and give in? Every time Cassie feels she has Frank figured out, he tosses several plot twists into her day that threatens to derail her best attempt at succeeding. Can she overcome the new challenges, or does she have to submit to his punishment? This is the fourth installment in Cassie's training. She has come a long way, but she still has a long way to go. Especially, if she intends to turn the tables on Frank in the process.
