"For the past five years, Bitterblue has reigned as Queen of Monsea, heroically rebuilding her nation after her father's horrific rule. After learning about the land of Torla in the east, she sends envoys to the closest nation there: Winterkeep — a place where telepathic foxes bond with humans, and people fly across the sky in wondrous airships. But when the envoys never return, having drowned under suspicious circumstances, Bitterblue sets off for Winterkeep herself, along with her spy Hava and her trusted colleague Giddon. On the way, tragedy strikes again — a tragedy with devastating political and personal ramifications. Meanwhile, in Winterkeep, Lovisa Cavenda waits and watches, a fire inside her that is always hungry. The teenage daughter of two powerful politicians, she is the key to unlocking everything — but only if she's willing to transcend the person she's been all her life."
