The Reckoning by Jade Presley

Two queens.
Their kings and assassins.
An entire realm under siege.

Cari and Gessi have been through hell…and that was before General Payne attacked them. Now that he’s stolen the Shattered Isle throne, he’s redefined the term suffering. Until his head is on a platter, it won’t be enough for the queens to save as many innocents as they can from their refuge in the Onyx City.
But when enemies come out to play, Cari and Gessi face immeasurable odds, and it’ll take more than their friendship to save them. Even with the help of the All Plane Kings and the Shattered Isle Assassins, they hit too many crossroads. And if they can’t get past those, their realm won’t be all that suffers.
