Edge of Darkness — Jessica Jarman

How far is too far? Where is the line that can't be crossed? For Merlin, when it comes to Anna, the answers are easy. Too far doesn't exist, and the uncrossable line has gotten pushed farther and farther away through the centuries until Merlin doesn't see it anymore. And that becomes ever more clear to everyone as a new threat rises. Being back with the Circle, back with Merlin -- where she belongs -- Anna should be happy. Her magic, finally free and within reach, and her memories following quickly, should be cause for celebration. But all of that is overshadowed, tainted by Mordred and the connection he's forged between their minds. With Mordred in her head, taunting and manipulating her at every turn, Anna fears she'll never truly be free. Though his days as King of Camelot and High King of all of Albion are in a long, distant past, Arthur has never felt the weight of his crown as heavily as he does now, in this life. While having Anna with them and being able to complete the Circle for the first time since Camelot is an advantage Arthur cannot discount in the battle to come, the odds are certainly not in their favor. Not with an enemy who seems to always be one step ahead. Not when the trust Arthur and the others have built over lifetimes together is dissolving beneath lies and secrets. The Circle is faltering, and Mordred's increasingly bold attempts against them are pushing them to the breaking point. If they can't return to their former strength -- back to the stuff of legends -- to defeat the powerful Magical, someone may pay the ultimate price before the final battle even begins.
