Secrets of the Bear’s Den by Milly Taiden

One night changes everything for an artist and her bear shifter mate.

Human artist Lillian Robinson is a fun-loving spirit who knows what she wants in life and in love. Unfortunately, she hasn’t found it. Most men just don’t measure up. Then Oliver walks into view, and she knows instantly that he’s the one that she wants. He’s strong, sexy and has a smile that makes her melt. The problem is he’s not human.
Oliver, the billionaire bear sleuth leader, has life just the way he wants it. He’s no-nonsense and business minded every day, with one exception: the full moon. That’s the one night a month he allows himself to attend a masquerade and let loose. When he sees Lillian, he has to have her. She’s spunky, fun and he can’t wait to get her out of her clothes.
Both Lillian and Oliver have intense attraction to one another, but figuring out their relationship will have to wait, because Lillian has an obsessive fan. Before they know it, Lillian in life-threatening danger. Nothing Oliver does can save her except fighting to the death. It’s kill or be killed if he wants to keep his mate.
