The Enemy's Daughter

"It's been thirty-seven years since the Republic was destroyed. Now two settlements--the five clans and the Kingsland--fight for control of the untainted land. Though the five clans are outnumbered, they've finally struck, killing Kingsland's brutal leader. In the war that follows, Isadora, an eighteen-year-old healer, risks her life to help injured soldiers. But when she stops an attack from Tristan, a Kingsland assassin, his soldiers shoot her with a poisoned arrow. As Isadora lies dying, Tristan does the unimaginable: He offers to save her life using a rare magic. In choosing to live, Isadora is unknowingly bound to the mysterious Tristan. Worse, even acknowledging the attraction between them allows him to glean fragments of her memories and the very knowledge he needs to destroy the five clans. But their magical connection works both ways. So to save her people, Isadora will have to open her heart to her most cunning enemy. Because in a race for ultimate survival, she'll need to destroy Tristan and his people first."-- Amazon.com.
