Blood Vengeance by Yasmine Galenorn

When Maddy and Aegis go on vacation, a blast from the past threatens to destroy them both.
Maddy and Aegis need to relax after opening the Bewitching Bedlam B&B, so they go on a post-New Year’s trip up to a mountain chalet. But what neither realizes, is that a dark cloud from the past is shadowing them both, and a resulting avalanche holds them hostage, at the mercy of a menace from Maddy’s past, who is ready to destroy Mad Mauldin and all she holds dear.
