Bad Boy's Bard — E.J. Russell

Niall O'Tierney, half-human son of the Unseelie King, had never lost a wager until the day he swore to rid the Seelie court of its bard. That bet cost him everything: his freedom, his family -- and his heart. When he's suddenly face-to-face with Gareth at the ceremony to join the Seelie and Unseelie realms, Niall does the only thing inhumanly possible: he fakes amnesia. Not his finest hour, perhaps, but he never revealed his Unseelie heritage, and to tell the truth now would be to risk Gareth's revulsion -- far harder to bear than two hundred years of imprisonment.

Then a new threat to Gareth's life arises, and he and Niall stage a mad escape into the Outer World, only to discover the fate of all fae resting on their shoulders. But before they can save the realm, they have to tackle something really tough: mending their own broken relationship.
