The King's Heart (King's Tale #2)
Rowena Sudbury

Dafydd hates to disappoint his lover, but he is not sure what to do. Since he will not leave the keep, he renounces his position as king’s marshal, vowing to focus on the healing arts instead. Though Christopher continues to pressure him to travel, Dafydd staunchly stays at home—until his second sight shows him he could lose Christopher if he cannot face his fears. Determinedly, Dafydd sets out to prove he can master them.
When Christopher returns home to find Dafydd gone, he knows exactly what Dafydd must have seen. As he once promised he would, he follows his heart across his kingdom—but even if he finds Dafydd, he may not be able to heal the rift between them.
