Unclaimed Treasure by Layla Stone

Markov is not quite feeling himself.

He’s going into his mating heat, which he’s unaware of and ends up stranded on a planet…with a strange woman….for fourteen days…and Markov had no idea how he’s going to get through it without losing control. Basama was in the wrong place at the wrong time – or maybe she was in the right place at the right time? Either way, they end up in an abandoned cave when his heat hits. What could possibly go wrong?
