Darkest Before the Dawn

When the King of Camelot is mortally wounded on the anniversary of the Prince's birth, a distraught and desperate Arthur is willing to try anything to save his father's life: even magic.
For years, Merlin has ached to tell Arthur the truth; has yearned for Arthur to see him--and accept him--as he really is. Yet, something has always held him back, until now. For there is nothing that Merlin would not do for Arthur...even if if that something is revealing himself as a sorcerer in order to try to save Uther.
But the consequences of these actions turn out to be more far-reaching than anyone expects, and it isn't long before everything goes terribly, horribly pear-shaped.
