Favilla Hesperus, first child of the Leader of Alatus, is just two months away from turning 18, when she will grow her wings and perhaps meet her soulmate(s) too. Kept hidden away from the public eye since she was 10, her 18th birthday also marks the day she is presented to the people of Alatus, for the first time, as their future ruler.
Desperate for one last taste of anonymity and freedom before her Winging ceremony, Favilla decides to go out on the town and party like it's the last time she'll get to. Until a chance encounter with a stranger brings back memories she had fought so hard to forget, after which, of course, everything goes south.
For Favilla, though, it's all worth it.
After all, who knew rebellion could taste so sweet?
