Magic is Thicker than Blood

Alastair Stone figures using tracking magic to help Jason Thayer and his new wife Amber find a missing child will be a good diversion. At least it will take his mind off a summer that, without Verity around, is shaping up to be a lot less eventful than he'd hoped.

But when the boy's kidnapper turns out to be a mage—one who's using the public portal network to steal children for some mysterious purpose of his own—Stone, Jason, and Amber are thrown into a terrifying web of mystery, mad science, and deadly peril.

If Stone can't figure out who the kidnapper is and why he's obsessed with these children, it won't only be the kids who are in danger. As the shocking facts come to light and the madman sets his sights on his pursuers, Stone and his friends might not survive long enough to learn the sinister truth.
