Secrets Dark Whispers by Rachel Carrington, Calista Fox, Elisa Adams, Ellie Marvel

What's a mild-mannered alien guy to do when he goes into heat far from his home--and women of his species--and the only compatible female around is a rough and tumble Terran mining specialist who's a friend of his but, well, not exactly one to hop into bed with anybody, much less him? Answer: he courts her. The old fashioned Terran way, at least insofar as his research about the backwater planet can determine. Because if he can't seduce the tomboyish Sarai before his cycle ends, he won't get a second chance at love.
