  Summary

  Charlie Morningstar is determined to bring back the Helliday traditions of her childhood — Hellsgiving dinner, the Twelve Days of Sinsmas, over-the-top decorations, family activities, and her favorite part: Father Sinsmas himself.
  And she ropes the entire hotel into celebrating… especially her dad.

  But reviving the season comes with an unexpected side effect. Lucifer and Alastor keep getting thrown together. A lot.

  From shared kitchen disasters to cursed mistletoe incidents, hellish competitive nights, suspiciously sentimental gifts, a holiday dance, and one very ill-timed karaoke duet, the two demons find themselves circling something neither is prepared to name.

  Charlie notices. Angel definitely notices. Everyone notices… except Lucifer and Alastor themselves.

  A cozy, comedic, canon-divergent Sinsmas romance featuring a found family, holiday chaos, mutual pining, soft moments neither of them meant to have, and a Sinsmas Eve that changes everything.
