Testing of Tertius [EPUB ebook] 

Brian and Tertius are back, but this time, the stakes are higher than ever When Brian and Lianor receive a coded message for Merlin, the know it’s urgent that they take it to him at once. Merlin’s apprentice, Tertius, couldn’t be happier to see them, but Merlin quickly realizes that the news is more serious than anyone could have imagined: the dark wizard Urlik is back, and he has vowed to take over King Arthur’s empire and destroy all who oppose him. As Merlin attempts to contact an old mentor, he is tricked and falls under Urlik’s spell. Without Merlin, how will the three stand against the most evil power England has ever known?   It’s up to Brian, Tertius, Lianor, and their friends to rescue Merlin and save their world from Urlik’s wicked plans. But the wizard is cunning, and it will take all their strength, skills, and smarts—and a little help from King Arthur himself—to have even a hope of triumphing over evil.
