His Final Secret — M.R. Forbes

The fight is nearly over. His reign of darkness is reaching its end. The cure for magic has been discovered, and for Talon the truth of its source is more horrible than he could have imagined. Tormented by what he has learned and on the verge of falling from reason to madness, he leaves the Refinery more determined than ever to put an end to his tyranny once and for all. Oz has led Eryn and their companions deep into the mountains, to a place long buried beneath the stone. They have a plan to set the Empire free, but first they must find a way to escape the relentless pursuit of General Spyne and his strange and silent hunter. Battles will be fought, bonds will be broken, and his final secret will be revealed.
