Rapture (Crimson Forest, #5)

In the wake of the deadly demonic disease that has nearly wiped out the Bryxx in a matter of days, including his own mother, Devon comes up with a plan to stop the slaughter, but it means giving up his livelihood and freedom in doing so. He will have to leave his life behind and begin a new one in hiding, away from other immortals. 

Crysta, a strange immortal woman Devon met at random turns out to be the best thing that's happened to him in ages. She doesn't care what he is or what he's done, she just wants a companion and like him, she has nowhere to go.

Being shacked up with a beautiful woman isn't easy for Devon. Anyone who knows the guy, knows he's a major ladies man, but for some reason, he can't bring himself to make a move on Crysta. She brings out the best in him and he can't risk harming her.

Just when Devon thinks things can't get any worse, he learns his plan, the one that risked everything, hasn't exactly been a success. There's a new problem on the rise. The demons are killing off the remaining Bryxx and it's only a matter of time before they move on to the humans. He can't let that happen, even if it means risking his own life and his new found love in the process.
