Marked Sky: The Tempest Spire Series

By Rhea Sullivan

At Tempest Spire, the sky no longer feels like something riders command.

After the events that shattered everything Isolde thought she understood, the storms are changing-and so is she. What once felt like instinct now feels like recognition. The weather is no longer just dangerous. It is listening.

As the academy tightens its grip and old loyalties begin to fracture, Isolde is pulled deeper into the secrets buried beneath Tempest Spire's stone towers. Lucian is still determined to protect her, even as the rules they were trained to trust begin to fail. And every answer they uncover leads to a more terrifying truth: the storms are not becoming unstable.

They are waking up.

With the sky marked by strange new patterns and the academy desperate to preserve its control, Isolde must decide who she can trust-her commanders, the boy at her side, or the storm calling her name.

Because the more she learns, the clearer it becomes:

Tempest Spire was never built to master the weather.

It was built to contain it.
