Davin is a Delta-23 replicate, which means he looks like every other Delta-23 on the planet. He's bored seeing the same face every day -- each replicate is his twin, though he alone seems to ache for something different. When a prison ship crash-lands in the woods and the replicates are asked to retrieve the prisoners, Davin jumps at the chance to encounter a natural-born.
Trace is a hard man who has lived a hard life, and the moment the ship carrying him crashes, he takes the opportunity to escape. The last thing he expects is the replicate eager to get up close and personal with an escaped prisoner.
