Watchers by Dean Koontz is a really great work of fiction about Einstein, a dog with extreme intelligence that was created in a lab for military use, the people who come into the arc of his life, and the also lab-created monster, the Outsider, intent on killing Einstein and wrecking havoc along the way.
The lead human characters in the book are Travis Cornell, who becomes Einstein's owner; Nora Devon, who meets and then marries Cornell; Vince Nasco, a hired killer; the authorities searching for Einstein and the Outsider; and the lawyer and the veterinarian who assist Travis and Nora.Watchers is richly written, a really enjoyable read, and noted by Koontz as one of his favorite to write, and perhaps the book of his that fans most often bring up to him.
