An Alpha a Day by Harper B. Cole

Adam is not having a good day. First, he is attacked by a bear. Then, the beast turns into a man and informs Adam that he’s a bear now, too. But, when the doctor in the hospital tells Adam he really [i]is[/i] a bear, and offers to take him somewhere safe for the full moon, Adam doesn’t know what to believe. Just when Adam thinks he has heard it all, the doctor drops another bombshell: he believes that he and Adam are fated to be together.

As an immortal doctor, Nolan Craik assumed he had seen it all. Until Adam walked into his life. Nolan thought the hardest part of it all would be sneaking very dangerous, new shifter out of the hospital. He didn’t count on being expected to teach Adam about life as a shifter. And he never dreamed he’d find his true mate, after a century of waiting for his own, spent delivering babies for countless true mate pairs.

But the feral bear shifter who changed Adam is still out there, and when word comes that he may still be looking for Adam, Nolan is forced to take his true mate into hiding. He’s always preferred healing people over fighting, but when his mate is threatened, Nolan is ready to ‘bear’ it all.
