"Fire and Earth" by Meredith Mansfield

Seventeen-year-old Casora has been raised to be a fearless warrior, commander of the faceless war band known as the Deathless. Nevertheless, she and her company are helpless to stop the invasion of their homeland. Without a country, the Deathless offer their services as mercenaries to the next land attacked by the same raiders who conquered their nation.

As the youngest prince and the one least likely to be of use in the war, Tiaran is about to be forced into a political marriage to a girl he hates. Rather than be used to secure the loyalty of an opportunistic general, he secretly goes off to fight in the war himself. His first battle is about to be his last when Casora rides in to rescue him.

When these two unlikely partners join forces on the battlefield, they'll shake the foundations of kingdoms.

I really enjoyed this book. Casora is a Deathless because of a curse, so she's already chasing her own demons all while frantic to find out about what happened to her family.

Poor Tiaran. There's so much more to him than his older brothers give him credit for--or even Casora, at first. She just thinks he's one more burden she must bear. Awesome and unexpected twist at the end.
