Baugh, Laura VanArendonk. Shard of Elan ##1

He can save her life-if he sacrifices those he swore to protect. When the artifact intended to end an interdimensional war is damaged, a mage is trapped on the other side of the rift with her servant-and only bastard soldier Shianan knows the cheery young boy with her is really one of the monstrous enemy, disguised as a human. Ariana is one of Shianan's few friends, but rescue requires treason and betraying his people to attack. State mage Ariana struggles as a prisoner of war in a world of deadly magic and unfamiliar customs. Her only ally is her former servant, once again a renowned warrior caught up in political machinations. To survive, he'll have to renew the fight against Ariana's world. As their people's wasted armies brace for fresh battle, bastard, mage, and monster must set aside prejudices and rivalries to find an end to centuries of conflict, before they die as traitors
