His Metal Maiden by Michelle M. Pillow

Dragon-shifter Lochlann left home to avoid a war he didn’t believe in. Now as Captain of The Conqueror, in charge of a misfit crew, all he wants is to return without the label of coward. He’s been offered one chance at redemption: Find Margot, a noblewoman’s missing sister. The only problem is, the woman disappeared years ago, and his closest lead is a stunningly beautiful look-a-like droid crafted in her image. Alexis is programed to be everything he could ever desire, but getting her to reveal her secrets proves to be a true challenge for this alpha male.

Being a base model pleasure droid isn’t as glamorous as it sounds. Alexis can’t remember a time when she wasn’t the property of others. Multiple surgeries, and endless tests, have amounted to a life not worth living. When a pirate crew visits her facility, she sneaks onto their ship. Desperate not to be returned to her owners, she strikes a deal with the alluring captain. Pretend to be Margot in exchange for freedom.
