Rumour has it that the formidable ruler of all worlds, long believed to be dead, is back and is harshly enforcing his old laws - including the one forbidding schools of magic. As teachers and pupils flee, Tyen is left with no home and no purpose . . . except to fulfil the promise he made to Vella, the sorcerer imprisoned in a book. Tyen must decide what he is willing to do to free her. Elsewhere, Rielle's peaceful new life as a tapestry weaver has been shattered by a local war. As defeat looms, the powerful Angel of Storms appears and invites Rielle to join the artists of his heavenly realm. But what will he require in return for this extraordinary offer? A gripping fantasy adventure filled with danger, intrigue and forbidden magic. Perfect for fans of Robin Hobb, Brandon Sanderson, Patrick Rothfuss and Peter V. Brett.
