From the author: "Just two guys in love trying to make it in this world. Note: one of the guys is a seven foot tall alien, the other is a dangerous redneck, and the world involves a lot of spaceships."
From fail-fandomanon.dreamwidth.org: "Two married mercenaries, one human and one not-human, take a shady job for fun and profit. Sweet, funny, bro'd up interspecies domesticity in spaaaaace."
- fairyninjas.wordpress.com: "a curious sci-fi story, where the pairing is one human and one alien. The tone of the story is low-brow, and it’s just overall a bit of random sci-fi fun."
