Ember's Moon: A Fantassy Tail of Naughty Princes and Duke's Animals.
Fairy Tales are always "tongue in cheek" but also include both sets of cheeks. This one is very challenging with fate twisting opportunities and love between friends, families, royals, animals, desires, missunderstandings, horse stalls, royal balls, sexuality, poverty, crowns, gowns, clowns, purpose, hunting, shepherding, caring, sharing, protecting, weather, parades, babies, stepmothers, sisters, hiding, fairy goddesses cracking the whip, and drunken townspeople celebrating anything.
The point where Cinderella, Cinderfella, and the Christmas story crash together and mix up your mind until you forget who is using which name and witch who is pretending to be someone else to confuse the thickening sheep herd by the prince in wolf's clothing.
You just have to read it to find out how a midwife deals with a male omega in labor in a remote cabin during a blizzard and a full moon without the father present in useable form.
