Alien Shield by Ursa Dax

SERENA
To say I’ve been busy is an understatement. Between trying not to die on this hostile alien world and helping my newly-pregnant friends (I am a biologist, after all) I’ve had a lot going on. But when I stumble into the alien forge and find the huge, quiet weapons master Xyan there, I have a whole new task at hand. Xyan – the biggest, strongest, most serious alien I’ve ever met – offers to help me study the Sea Sand biology. I may be busy, but not too busy for that. I mean, who could refuse the opportunity to study the anatomy of a gorgeous alien man up close and personal? But the more time I spend with Xyan, the less academic my interest in him becomes.
I’m falling for this stoic alien warrior. But he’s totally unreadable, and he hasn’t said anything about having a mate.
Even so, I can’t help but feel there’s something between us.
Maybe I can still love him even if he isn’t meant to be my mate.
I just have to figure out how to keep my heart in one piece in the process…
