The Royal Four — Amy Stout

In her stunning debut novel The Sacred Seven, author Amy Stout gave us an enthralling adventure replete with all the magic and heroism, mystery and power of the best epic fantasy. Now, in The Royal Four, she transports us back to a kingdom known as the One Land where, for one brief, golden moment a ruthless conqueror was vanquished and a long-awaited peace reigned...

...For but an instant. Now a vengeful elfwitch and her monsters endanger a harmony that was dearly and bitterly won. And a young mercenary and her dragon brother, so recently revealed as royal heirs and transformed to claim their rightful thrones, find their birthright imperiled yet again--as they come face-to-face with a hidden poison in the royal bloodline that threatens to beget a nightmare of cruelty, devastation and darkness that will endure for all eternity.
