Madeline's Mates by Evangeline Anderson

Madeline Grant leads a lonely existence. Growing up an orphan, she’s never felt she belonged anywhere or to anyone. But all that is about to change.

One snowy night, a huge man with piercing blue eyes comes into the ER where Maddy works. He takes one look at her and tells her she’s about to go into heat. Maddy thinks he’s crazy -- until his strange predictions begin to come true. But inviting the man, Jake, into her life, throws her world into a whirlwind of confusion. As if the news that she’s a shapeshifter isn’t enough, she also has to breed with her own kind -- which means that no matter how much she desires Jake, he’s forbidden to have her.

Enter Jake’s best friend, Will -- a shifter of the same breed as Maddy. He wants her at once but her heart is already taken. Thrown into the dark and dangerous world of shifter taboos, Maddy must decide whether to follow her head or her heart as she tries to survive the Christmas heat.
