VALLEY OF THE VIKINGS (PB)

Neptune and Thor battle for power and their fight upsets the balance of the world. Towering waves swallow a Viking longship and its crew into a watery valley, taking with it the secret of the magical crystals. A thousand years later, Emily, half human, half mermaid, discovers a bangle with a mysterious crystal. She learns the truth about the jewel - and the danger the world faces. She must now persuade the powerful and selfish gods of sea and sky to make peace with each other, before disaster strikes.
