Wolf at the Door (The Others, Book 9)

Sullivan Quinn didn't travel 3,000 miles from his native Ireland and his wolf pack just to chase rabidly after the most delectable quarry he's ever seen. Quinn is in America on a mission--to warn his Other brethren of a shadowy group willing to use murder and mayhem to bring them down. But one whiff of this Foxwoman's delicious honeysuckle fragrance and he knows that she is more than a colleague or a conquest…she is his mate.
Anthropologist Cassidy Poe is a world-renowned authority on social interaction, but the overpowering desire she feels around Quinn defies every ounce of her expertise. Working by his side to uncover The Others' enemies poses risks she never expected--to her own safety, to those she loves, and to her heart, as every encounter with Quinn proves more blissfully erotic than the last…

Now, with no one to trust but each other, Quinn and Cassidy face a foe that's edging closer every day, threatening to destroy the life they've always known, and the passion they've just discovered…
