I remember reading this when it was free. I give it about 3.5 stars, I guess: it was solidly OK, and depending on what kind of fiction you like this might be great for you. It can be hard to find gay scifi romances. I read it with half my brain activated, and I profess I have a fondness for a bit of 'fanficlike' 'comfort food' writing now and then. This is one of the better writings in that category, although I've read better, honestly.
edit:
Looking back, I only barely remember this novel at all, and not with great feelings. Not a good sign for it.
