Alien Body - Phane, #1

In Alien Body (sci-fi, 80, 000 words), Physician Dave Booker is shocked to discover an alien living in his summer cabin. Phane, the alien, is an anthropologist from another star system. His shuttlecraft has crashed, and he must regain it before the mothership gives him up for dead. But Dave is dumbfounded by the alien's appearance, a large, green tennis ball with two eyes on tentacles above his head.
Dave's ambitious boss captures Phane, but he escapes. In a wild chase, Phane flees determined pursuers including the military, but it's not easy for a talking green tennis ball to hide. Dave realizes that Phane has much to teach humanity, but can he find his alien friend in time to help him?
