The conclusion to part three of the epic Runespell series. A lucky subterfuge has fooled the Golden Dragon into leaving Opal Island; and she has trailed the Pisceran Porpoise out to sea believing that the newly-repaired Chalice of Ond – the only hope of resurrection for her precious golden son – is hidden beneath her decks. On board, amidst the dragon-attacks, Lord Casper worries for his own son, Rollo, abandoned on the hob-infested rock. But Rollo has the real chalice in his possession and although the responsibility weighs heavily, he must find a way to elude Silas's minions and travel across the ocean to find his father – if Isolde is ever to regain her humanity, to reunite Aranthane with his wife or save Leaf's dying people. Rollo must learn to harness the strange power which lies unpredictably within his body to ensure that Silas's invasion of Belbidia is stopped and that Torra Alta, the only home he has left, is rescued.
