Shadow Hunters - Linda McNabb

Have you got a shadow? Then hold onto it... before it betrays you! Elves who live secretly in the midst of the human world are known as shadows. After a near miss on the king during a royal hunt, the rumour is spread that the elves were trying to kill the king. Now elves live in constant fear. The king's shadow hunters seek to capture and lock them up. Rhonan and his sister, Dyahn, are half-human half-elf and when they sneak away to play with the wild ponies on the moors, they accidentally lead the shadow hunters back to their family. In a twisting, turning tale of dragons, magic stones and broken promises, they must try to save their parents from the wrath of the king. This story is best read after The Dragon's Apprentice - but stands alone as well.
