Prince Amara (placeholder name) is a shapeshifter but his egregiously arrogant father doesn’t know. With a stigma against shapeshifters, Amara hides his ability in secret. All is well till the king (his dad) hired a gardener who finds out and snitches to keep the better name of the royal family, but is secretly admired by his abilities.

(Possible animal kingdom of sorts? Just an idea.)
