Forbidden Honor by May Dawson — book slip

Honor is an orphaned servant expected to shift into a squirrel, but instead, she becomes a dragon shifter, throwing her world into chaos. Disguised as a man, she joins the Royal Dragon Guard, where the dragon nobles are less than welcoming.

By day, she is Lucien Finn, a despised dragon shifter; by night, she is the maid who captures the attention of the royal princes.

As she navigates the dangerous world of dragon politics and military training, Honor must decide whether to follow her heart or maintain her disguise. Can she survive the royals' games and reveal her true identity?

First in the Dragon Royals series.
