The storm is coming?and it doesn't care who stands in its way.

Lily Starling thought she'd finally found her place among the stars. But when a routine rescue mission turns into a devastating ambush, she watches in horror as the Storm Riders?a ruthless band of spacefaring raiders?vanish into the chaos, taking her closest friend with them.

Now, with the Salamander crippled and the galaxy on edge, Lily must convince her crew that the Storm Riders are more than just pirates. They are zealots, wielding the power of a cosmic tempest the Union refuses to understand?one that may have been set in motion long before Lily was even born.

As the hunt takes her to the farthest reaches of known space, Lily must rely on unlikely allies, question everything she's been taught, and face the growing storm within herself.

Because the leader of these zealots is hiding a dark secret.

And if Lily can't stop them, the storm will swallow everything.
