Stormspire: The Blood King's Door (Hardcover) (ISBN-13: 9798295544408)

Kaela never asked for power.

She only ever wanted to survive.

Raised in a world that broke her before it ever tried to understand her, Kaela learns early that strength is the only thing that keeps you standing. But when a storm unlike any other awakens something inside her, something ancient, something dangerous, survival is no longer enough.

Taken to Stormspire, a fortress carved into the heart of a lightning-wracked mountain Kaela discovers she is not alone. Alongside her sisters, Seren and Mira, she begins to uncover a power that was never meant to return.

Because far beyond their world, something is waiting.

The Blood King, an ancient force of corruption, has begun building a door of his own. A door that, once opened, will allow him to fully cross into their world and finish a war that was never truly ended.

And the only thing standing in his way...is the storm itself.

But storms don't just destroy.

Sometimes, they choose.

As the line between worlds begins to fracture, Kaela must decide whether she will control the storm...or become it.
