voices in the void: book two of the crystal key trilogy

Abby struggles to fit into an unfamiliar world as an untrained, rogue witch. This is a world in which magic is real, jealously guarded by those with the power to wield it. His friend Dacy, now transformed into a fairy, desperately wants to be changed back into a human.
All the time, they are hunted by those who wish them harm, and those who want to use them for their own ends...
And in the void between worlds, a presence watches over them all. Will Abby find there a friend or foe?
