When Sierra Garrison’s isolated world collapses,

survival becomes something far more dangerous

than she ever imagined.

The station falls.
Her medicine is gone.
And the mist that should have killed her does

something impossible—it binds her to the enemy

prince sent to destroy her.

Now their lives are tied together.
If she dies, so does he.

As violence spreads across Achlys and the balance of

the planet begins to fracture, Sierra is pulled into a

mystery far older than anything she was meant to understand.

The Thrones are failing.
The world is breaking.
And the truth may cost more than either of them can survive.
