SPRING: When Iris’s sister ends her engagement to the Valentine’s Day prince, the truth comes out about who’s really keeping Easter afloat: Iris. But is finding meaning for her Holiday the only thing Iris wants . . . or does she want her friends-with-benefits relationship with the St. Patrick’s Day Princess to mean something, too?
SUMMER: As Iris and Finn fight for their second chance, the St. Patrick’s Day King mends the bonds broken within his family. But the strongest bond is the one Loch has with the soft-hearted Prince of Christmas, and an ancient Irish festival will let him seal it for the rest of their lives.
AUTUMN: Another question gets asked at the annual Halloween celebrations, and Halloween’s heir wants to say yes to the Christmas King—but merging two Holidays is impossible. Hex will have to choose once and for all: his future or his Holiday.
