When the half-demon Carter approaches Menolly and her sisters desperately asking for their help, they think he's just had a tiff with Shimmer, his blue dragon girlfriend.

But after talking to Alex Radcliffe, the owner of the Fly By Night Magical Investigations Agency where Shimmer works, they suspect that she has been kidnapped by an old enemy of Alex's.

Now, Alex must join forces with the D'Artigo sisters in a desperate race to find Shimmer before Julian, a powerful vampire from Alex's past with a grudge to settle, can use the dragon to wreak havoc on Seattle as revenge.
