Vixen / Echo. Isolated Showers, #6

Vixen, a soldier who's obviously not like the others, is now a prisoner of war. His caretaker, known only as Echo, is too. Or maybe she's flipped to the other side. Injured, isolated from the outside world with no other knowledge to go on and fearful of a plot to get him to spill information, Vixen must use the only tool at his disposal- the simmering sexual tension between him and the only other person around.
Of course, that itself might be part of the plot.Matthew Atkinson locks you in with a tense, steamy but non-erotica SHORT STORY from his collection, Isolated Showers, in which minds can get screwed harder than bodies.
