Onyx Necklace - Book Seven of the Seven Stones of Power

Only one Dark Knight remain, but that is enough to cause problems for the Alliance. Even the Council of Wizards are cautious to face such an adversary.
With the final battle close at hand Alaric has to find the Onyx stone if he is to have any chance against Nyrra. He must conquer all his fears if he is going to succeed.
The Alliance is in Remidia, but needs to travel to Avalon to embattle the Evil One's hoards in the final battle. The first time was a ruse, but there is no doubt this time the final battle will be won or lose.
