Intrepid young travelers reach their destination in time to face a perilous battle in the thrilling conclusion to this acclaimed YA trilogy.

Emmeline and Matisa have arrived at the land of Matisa's people, but the Dominion's troops are moving in. Matisa's people have prepared for battle, but the Dominion's weapons are brutal. To secure their survival, they will need something so important the Dominion will have to leave them in peace. Matisa and Em think they know what they need: the remedy to the Bleed, a deadly sickness.

To find it, Em will have to go back to the stifling settlement she'd spent her whole life trying to escape. But she's no longer the Stained girl she once was--and she's not going down without a fight.

Heartfire concludes the acclaimed Winterkill trilogy, which includes the novels Winterkill and Darkthaw.
