Exile (Forbidden Things, #2)

The Lyran prince stands accused of a terrible crime against Indigos country. She wants nothing more than to prove the accusations false, but evidence puts the blood on his hands. While trying to protect him from the swift descent of Caithin justice, Indigo uncovers the workings of an enemy willing to do anything to see the prince dead. An enemy who currently has the upper hand. To make things worse, an army is marching on Lyra. One that uses ascard power in ways never seen before. She is determined to prove the princes innocence and convince Caithin to go to Lyras aid. That might be easier if he wasn't missing.
