Unexpected by R.L. Olvitt

Two pairs of best friends—one alien, one human
Two sets of lovers—one genuine, one pretend…until the moment they touch
Reesi has been in love with her best friend ever since she was a young girl running the streets of Fassalthi. With his dark, broad wings and vivid green scales, Taeth is the perfect example of Lisseethi masculinity. He’s all she’s ever wanted—until he decides to search for love among the humans.
Soon Taeth is making plans to travel to Earth to be with his human lover, but bold, vivacious Angie Rodriguez has a best friend, too. David Alcantara has been holding a torch for his childhood friend for as long as he can remember. When Taeth and Angie push him to pursue Reesi, they both agree to a correspondence to appease their friends. Neither one of them is looking for love, but they’ll pretend. If faking an attraction they don’t feel shows Angie and Taeth what they’re missing, the charade will be worth the effort.
The trouble is that pretending isn’t so easy when friendship starts to feel a lot more like love. The instant they meet in person, attraction flares between them like wildfire, but the chemistry they share swiftly becomes something far deeper. When Reesi’s health and safety are threatened, David will need to decide if keeping a love he never expected is worth the sacrifice of his friends, the life he’s built for himself, and the only home he’s ever known.
