Alien Attraction [Gay ménage romance]

Reece just wanted to spend one uninterrupted picnic with his husband, Nathan. A huge blue-green man falling from the sky and crushing their car was not on the menu, but getting shot in the back when he tries to help is the last thing Reece expected.
Jaak is having a strange day. Not only did the humans try to kill him using an old-fashioned hand grenade, but the man who attempted to treat his injuries is now fighting for his life. Jaak can't just leave the human behind to die, but a blood transfusion with a Kalpattaan means more than just saving the guy's life.
How on Earth is Jaak going to explain to Basten, the man he's loved for years, a man he's never quite gotten around to marrying, that he's not only bonded to someone else, but that his new husband also came with a husband of his own as well?
