Heartseeker by Melinda Beatty

Wow. I loved it! Only is a very special girl; she can see lies, and to her, they’re beautiful. She has told no one of this power except for her grandmother and she doesn’t intend on telling anyone else. But one day, a servant of the king finds her out and Only is shipped off to the palace, far away from her family and her orchard. On the trip across the kingdom, she makes friends with Gareth, a steward, and Bethen, captain of the army. The palace is dangerous, and Only must save everyone—even if she’s not sure she can. One more thing, Only gets violently ill if she tells a lie of her own. Happy Reading!
