'In a desperate race against the Dark, Maerad must try to solve the final riddle of the Treesong. Only then will the Nameless One be defeated and peace restored to the Seven Kingdoms. But Maerad only holds the key to half the riddle - her long-lost brother, Hem, has the other.
'Before embarking on a perilous journey to find Hem, Maerad must first wage an epic war against the Landrost. And Hem, fleeing the advances of the Black Army, must endure betrayal and mortal illness in his search for Maerad.
'But the Dark grows ever more powerful - will brother and sister reach one another in time or will all be lost in a final, apocalyptic battle?' (Publisher's blurb)
