Duel Citizenship by Cassandra Chandler

Vegans Welcome.
Living in a treehouse restaurant in Florida, Sarah expects to encounter plenty of wildlife. But the huge lizards who suddenly show up in her tree aren’t the health conscious clientele she was hoping to attract when she expanded her menu to be vegan-friendly. She also didn’t expect one of the lizards to be determined to kill her.

Disguised as a tourist, the Sadirian soldier Ari is investigating strange readings coming from a huge oak tree in Florida—a tree with an Earthling living in it. The Department of Homeworld Security has sent him to find out if something extraterrestrial is going on, and with the Coalition looking to bring Earth into the fold before humanity is ready, he doesn’t have much time to sort things out.

Ari has been warned about the temptations of Earth, but nothing could prepare him for the full sensory overload he experiences with Sarah. From the first encounter with the most sensual meal he’s ever shared, Ari’s mission becomes more complicated. And if he can’t help Sarah navigate the mystery of her new reptilian companions, Earth will be in more trouble than he thought.
