Merlin's Cave

What happens when everyone's nightmare is about to destroy the helpless human race, when our only ally is a non violent alien trapped inside the body of an eight year old boy?

Col Frank Wyman, ex intelligence service pilot is about to find out when it is his son who is taken over, and Col Wyman is forced into his agonizing decision, his son or humanity. A decision all the more complex since he's just fallen in love, a love that jeopardizes more than the loss of his son.
