Hex’s Desire (Chaetdorian Mates #3) by E.M. Reders
Many centuries ago, the planet Chaetdor was destroyed, and the survivors of that planet set out on a mission to find themselves a new home. Earth was never part of the plan; a primitive world with little technology and a sun that was harmful to the Chaetdorian body. When there was a fault with the ship, they had no choice but to land on the foreign planet and hope that they could fix the problem quickly so they could continue their journey.
But that didn’t happen. The fault was far worse than they had first thought and caused them to crash during landing, severely damaging their vessel. With the lack of technology on Earth at that time they were stuck, having no choice but to hide their craft and adapt in order to survive.
There were just two problems. One, they were highly sensitive to the earth’s sun, meaning that they could only venture out at night. And two, to maintain a humanoid appearance they needed to consume human blood. Stories of large, handsome, pale men with fangs soon spread, and the myth of the vampire was born.
Now it’s time for them to leave… if only it were that simple.
