In this epic conclusion to the Seafire trilogy, Caledonia Styx will risk everything—her heart, her crew, and even her life—to defeat Lir and take back the Bullet Seas once and for all.

“A gutsy tale of sisterhood, courage, and unshakeable trust.”—Julie Murphy, #1 New York Times bestselling author of Dumplin'

“As smart, ferocious, and uncompromising as its crew.”—Kiersten White, New York Times bestselling author of And I Darken
The vicious warlord Aric Athair is dead. But the fight for the Bullet Seas is far from over. Caledonia’s nemesis, Lir—the man responsible for destroying her family—has seized control of the warlord’s army and rendered the seas more dangerous than ever.

Caledonia and her crew have fled to Cloudbreak to prepare for an all-out war. And they are not the only ones. Rogue ships and even a few defecting Bullets show up to join their fight. But Lir is always one step ahead of Caledonia, anticipating her every move as he secures the seas for himself.

With the fight growing desperate, Caledonia is forced to make an unlikely and unsteady alliance with a new enemy, one who hates Lir almost as much as she does. It’s a terrible gamble that could cost her dearly, but with the fate of the seas in her hands, Caledonia must risk everything—and everyone she loves—to win the war. Will she finally defeat Lir . . . or will the greatest battle of her life be her last?
