Jacinth, Miranda and Jack live in different lands, yet are all connected. Only by combining forces can they turn around the curse that has befallen their families for generations. A group of knights violently wrested a revered relic from an African tribe long ago. Our three protagonists are each descended from a knight - and each of them has a duty to return the stolen lily which gave the knights amazing powers. Powers that have warped and darkened over the centuries, leaving only instability and death in their wake. But a renegade ancestor is determined to retain the lily's power and influence - whatever the cost - and all three children are in terrible danger...
