Ray Kilbride has found himself back in his hometown after the sudden death of his father. But besides all of the normal things that come with settling someone's affairs, Ray also has to deal with what to do about his younger brother, Thomas. Thomas has schizophrenia, and doesn't leave his room voluntarily other than to eat and shower. He spends all of his time online, walking the streets of the world's cities on Whirl360, a Google Maps-esque program. He's not only "walking" the streets, he's memorizing them, because he believes that the CIA and former president Bill Clinton have hired him to be prepared to be able to recreate these maps after a coming global catastrophe.

But one day Thomas sees something on one of those maps that wasn't meant to be seen, and a chain reaction of events is kicked off that will change life for the brothers forever.

I generally like Barclay, though I wasn't sure about this one at first. It took a while for all the different pieces to come together and form one picture, but it kept me turning the pages. There are also a couple of little side mysteries within Thomas and Ray's personal lives that were compelling.
