Black Sky Morning by Hanna Dare

A bounty hunter in over his head.
Xin knows how to look out for himself, and he knows when something sounds too good to be true. But a forgotten planet filled with riches is too tempting to pass up. Fortunately Xin also knows someone who can back him up – if he doesn’t arrest Xin first.
A government agent who’s lost hope.
Jonathan Gray used to believe in a better future. Now he’s not so sure. Then Xin walks in, with his dark eyes and maddening smirk, and Jonathan feels like he’s waking up for the first time in months. Well, parts of him at least. He knows Xin is trouble, but when trouble looks this good it’s impossible to resist.
Two men. One dangerous planet. To survive they need to trust each other – too bad neither of them does trust.
