Calamity by Toshi Drake

With the planet on the brink of erupting and his memories gone, can Commander Damon Wild find his way back home?
Commander Damon Wild is not having a good day. Being shot down on a remote planet by enemies and then losing his memories is enough to make a good man desperate. But when his situation becomes worse—a planetary eruption—Damon knows he has to do something. A small scientific outpost at the centre of a caldera offers something he’d only dreamt about, hope.

Captain Zaveid L’eau offers Damon a place to recover and space to find himself once more. The attractive captain distracts him from his troubles and it’s enough. Damon can see the light at the end of the tunnel and Zaveid is the one lighting the way.

But with a volcano on the brink of exploding, Damon doesn’t have time for peace.
The pirates are breathing down their necks and a massive eruption destroying everything, Damon has to learn to trust Zaveid with his heart and that no matter the circumstances, love will give them the strength to defeat all enemies, including their own self-doubt.
