A Drop Of Fire.
July. Almost seven months since the Old Religion case, and Merlin's reputation is in tatters, Mordred has returned to London, Morgana's been released from prison and Arthur's left in the dark about everything he cares about: Merlin.
The mystery death of a politician sends them all into the waiting arms of a hunter, all the while their pasts, the familiarity, is no longer just a feeling for Merlin. He knows. He remembered. Arthur hasn't.
The magic has grown, and Merlin with it, for better or for worse.
