I thought this sounded cute and a fun last smutty venture into Christmas/holiday romance for the year with a little Omegaverse, and I really enjoyed it! I don't know if I've ever read one where all the Alphas are essentially strangers to each other and have to decide if they're going to become a pack. It was a whole other layer of tension and I kind of loved it. Knox, Micah, Gunnar, and Zane all end up snowed in with Emma at Knox's giant A-frame cabin/mansion where he prefers to be a hermit with only his dog for company. She's an omega and has run away from the wedding she was supposed to have with a pack that a matching service said should be super compatible but then were awful.  Then she scent matches with all four of the guys who rescue her. It's smutty, has some good emotional arcs for all of the main characters, and two of the alphas also are drawn to each other (aside from a couple pet names that aren't for me, my main "complaint" is that I wish we got more about them together, even though there was a decent amount, I'm just greedy). This is the most recent in an ongoing series, with three previous ones I will definitely be adding to my KU queue immediately. 

Update: the bonus story you get for subscribing to the author's newsletter has more of Gunnar and Zane's relationship development that I was wishing for!
