Love on the Korlyan Moon by Petra Palerno

LENA

When the aliens who kidnapped me dropped my bubble into the ocean of an alien moon, I really thought I was a goner. I thanked my lucky stars when Kitaico, a bizarrely hot, tentacled alien, rescued me from what would have surely been a watery grave. There's one big problem though, I accidentally took his mating sting. So, through no fault of his own, we both have to deal with my forced heats thanks to his venom. Can I fight my chemical-induced attraction enough to work out if I want to spend forever with Kitaico?

KITAICO

With only a short time left until I can complete my Great Proving and be found worthy of one of the few female mates on my planet, Lena drops into my lap. I don't understand how the Great Mother could give me a mate who can't mark me in return, but I know there's something special about this human. Will I be able to resist her during her heats and somehow show the elders that I'm worthy of Lena?...
