Realm of ash
(Book)

Includes Extras, including an excerpt from The Throne of the Five Winds by S. C. Emmett and The Sisters of the Winter Wood by Rena Rossner.

The Ambhan Empire is crumbling. A terrible war of succession hovers on the horizon. The only hope for peace lies in the mysterious realm of ash, where mortals can find what they seek in the echoes of their ancestors' dreams. But to walk there requires a steep price. Arwa is determined to make the journey. Widowed by a brutal massacre, she's pledged service to the royal family and will see that pledge through to the end. She never expected to be joined by Zahir, the disgraced, illegitimate prince who has turned to forbidden magic in a desperate bid to save those he loves. Together, they'll walk the bloody path of their shared past. And it will call into question everything they've ever believed...including whether the Empire is worth saving at all. --from Amazon.
