Yay! The M/M world needs more good (humanoid) shape-shifting stories like this one. I've been jonesing since reading one back in 2009 that I loved and unable to find many since. 
 So, how exactly do you find a shape-shifter, who can take on any humanoid's form, and then bring him in, when you know next to nothing of his species? Down-on-his-luck retired and crippled war veteran Kyle will have to figure that out on his own when he's tasked with just such a mission. He knows the fugitive's method of escape. Now he just has to figure out who on board is his 'man.' 
 As he figures out who his mark is, he is slowly seduced by the idea that just maybe the problem isn't his malfunctioning body or the sector on the cusp of war. If only he can see past the prejudices created by society and himself, he might come to truly grok that who you are has nothing to do with how you look or the body you're in. 
 Which is a good thing, in the end, because he's in for a wild ride after this. =) 
 I would enjoy reading a sequel to this at some point in the future.
