The Secrets of Jane: Forgotten (Improper Bastards Book 1)

When she has bounty on her head, and he's a morally black mercenary that seeks her out... until he's forced to be her bodyguard. A dark, gritty world full of pirates, mercenaries, and thieves. Enough steam to fog your phone, while laughing at the true-enemies-to-lovers banter, then gripping it because there *will* be heads rolling.
