Good ol' star-spanning cosmic world-building, with Lovecraftian undertones. It has a lot to do with brain-riding and hacking, and a loss of reliable perception--- it's a little disjointed to read, at first, because you're supposed to be as lost as the character is, with what is real and what is not, and it only devolves more and more, as it goes on. (He's the fallout result of a forced melding of a synthetic and rather innocent biological sentience, resulting in a lack of definitive identity.) There's a lot of "eye candy," with the landscaping and delving in to incredibly complex alien cultures (I've been world-building for this singular project for over 12 years, so I know it like the back of my hand.) I am overjoyed that the good folks at Nightshade Books are giving me some love, and I hope I can bestow it upon all those who pick it up.
It's called "This is Paradise." Check it out, if you'd like--- well, when it releases.
