The Kelly heir has been found at last. Hidden in the hills of small-town Rio Seco, Texas, Keira Kelly’s changeling manifestation has finally taken place - but a little early and with some unusual characteristics. Expecting to come into her own with only one talent — most likely a shifter — all of the talents of her heritage have been becoming equally strong in her, and she is thus heir to the Kelly throne. Now Keira and her co-ruler, Adam, just have to get their new court established. Nothing, though, is ever that easy in Rio Seco.

Keira’s arrival home from Vancouver is met with news of the closest werewolf pack’s relocation to Rio Seco and the troubles they've been experiencing at the hands of unknown foes. A new, rather large and quite vocal church has opened up on the outskirts of the werewolves’ territory and has begun infiltrating the neighboring town’s school, government, and police. Additionally, there could be a traitor within the werewolves’ pack. As heir and ruler to the territory, Keira is forced to deal with the festering problems, but the price of her aid will be high.

The combined strength of the Kelly clan members, vampires, werewolves and royal court should be enough, yet Keira can’t help feeling that the easygoing lifestyle she loved so much in Rio Seco has vanished forever. The pomp and circumstance of her position are not only demanded by her Queen but are also necessary to create an air of greatness and power that will awe other strong foes. Regardless, one would still waltz into her court and demand war for her throne.
