The falcon was on top of her, talons clamping around her body. Ivy screamed, as much with fury as terror, and struggled to escape. But the bird's grip only tightened, and pain stabbed through Ivy 
as the cruel, hooked beak came down for the killing blow...

Exiled from her underground home by Betony, the jealous queen of the piskeys, Ivy sets out to make a new life for herself in the world above—a quest that leads her to mystery, adventure, and a hoard of spriggan treasure. But a deadly poison still lingers in the Delve, and Ivy cannot bear to see her people suffering under Betony's rule. Yet Betony will not give up her kingdom without a fight... and when her evil threatens the friends and family Ivy holds most dear, it will take all Ivy's courage, daring and determination to save them.
