What this book is about

Dylan O'Conner, his autistic brother Shepherd, and a comedian named Jillian Jackson are injected with an experimental nanotech substance by a frightened scientist in a roadside motel. The injection gives each of them different perceptual abilities — and makes them targets of the people who want the technology back. Dean Koontz's cross-country thriller has the propulsion of his best work and a particular warmth in the relationship between Dylan and Shep, whose autism is rendered with specificity and tenderness.
