Oh. Man. This one got me right in the feels. 
 Trevor is a successful artist in the end stage of renal disease. He's been on dialysis for the past seven years in the hopes of finding a suitable donor, but his kidney function is failing and he probably has less than a year to live, even with dialysis. He's 39 and facing his mortality. It's creeping up on what will likely be his last Christmas with his large and loving family, but his flight is cancelled when a blizzard grinds all transportation around Denver to a halt. 
 Marc is a driven attorney, hell-bent on making partner at 38. He's sacrificed his entire adult life to be the kind of son his homophobic mother would be proud of, only to note that he has no life except work. Stranded in the white out, he makes his way to a nearby hotel and books a room for the night. Seeing Trevor in the cafe, Marc is immediately attracted. His invitation to sit and join him becomes a long conversation and a further invite to share his room once Trevor confesses that he was unable to get a room due to a sell-out. 
 Neither man is really open to more than one night's solace, despite their incendiary passion. Trevor hasn't had a partner for years, and he's had even less of a libido for most of that time. Something about Marc stirs him, however. In the cold light of day neither Marc nor Trevor can admit they have more than lust boiling along, even if it's true. That said, Trevor doesn't want to reveal his illness and Marc knows a relationship will detract from his workaholic ways. Still, Marc can't abide with Trevor spending his Christmas Eve, and maybe longer, on a couch in the hotel's lobby. He invites Trevor to his beautiful and barren home outside Boulder. 
 Trevor's reluctant to let any connection build between himself and Marc, but it happen anyway. They spend a fantastic Christmas together, Trevor coming clean about his illness and prognosis when Marc presses him for more than their three day fling when he returns from visiting his family. It is bittersweet and melancholy and heart-wrenching and wonderful that these two lonely souls find a spark in such dire times. 
 I fully enjoyed the resolution to this one, which, I will state firmly, was an HEA. Marc's selfless offering of himself helped him to realize all that he had to offer others, and allowed him to break free of his self-loathing. I really liked how he engaged himself with his colleagues and found the best way to handle his very sad situation. Trevor is a man who has resolved himself on imminent death. He's afraid to hope one more, probably last, time. And it shows. He does find the courage to accept Marc's lifeline, however, and it proves the adage that life is always darkest before the dawn. 
 I just plain loved this. It's a well-told strangers-to-lovers story that doesn't ooze sap, despite the medical realities of the plot. The Christmas aspect was balanced, with high and low points--love, loss, isolation, acceptance. I will admit to shedding a tear, or three. As a person with an even rarer blood type than Trevor, I sympathized with his plight. (I may B- but I will always be positive!) There aren't too many sexytimes, but they are all about the feels. Highly recommend!
