Bedlam by M. L. Briers

Death stalked the little town of Trouble, but whose death?

Bonnie had a feeling her time was running out, and she didn’t want to tempt fate. Staying away from Jake or any other shifter was her only hope of staying unmated, or so she thought.
Jake was one part grateful, and one part annoyed that he hadn’t met his mate. Maybe fate just didn’t think him worthy? His bear didn’t like it either, and it was getting restless at the thought of never finding its mate.
There was a nasty surprise waiting for Grammy in her greenhouse, and for once it wasn’t the vampire. But was waiting for her in there, chilled her to her boots.

Were the wolves and bear shifters heading for a showdown?
Could this mean war?
What would that mean for the witches caught in the middle?
