With Cameron out of their lives for good, the Kaplans are ready to celebrate Yule, a time of spiritual renewal and giving thanks to the gods of their ancestors for the benevolence showed to them. Eoghan's and Gwylim's miraculously coming back from the dead, Aidan putting his traumatic past behind, Bennett coming home—these are only some of the things the clan is grateful for.
Eoghan and Phelan, now an established couple, have the approval of both families.except Niall, who still hopes to break them up somehow. Phelan has plans of his own; his fiancé is in for the surprise of his life, and so is the former elder of the Kaplan clan.
Carradine and Thorne, on the other hand, still hesitate to voice what they feel for each other, and Fionnuala is tired of putting up with her cold, arrogant husband, so different from her one true love.
Enter Graham, a ghost boy from the Kaplan family, who met an untimely death almost three centuries earlier, who decides to help the true soulmates find the way to each other's heart again and enrolls the help of Gareth, Thorne's son, and Methuselah, the resident ball python with a larger-than-life personality.
