The Shadow Beast — Russell Johnson

All is not boding well for Paul Garrett, a chivalrous teen who can stop time. He has used this gift to help the weak and oppressed, and he is a source of inspiration for the Garrett family, but they know nothing of his scandalous origins until a manuscript falls into the hands of Cassie Garnier. It was written by a time-traveling version of Paul who wants Cassie to assist him in defeating a shadow beast. The shadow beast is demon that has infected the mind of an evil time traveler named Travis. Amid the unfolding chaos is a dire warning from Paul's little sister, Emily, who has prophetic dreams. As the growing palpable sense of impending danger intensifies, so does the feeling that everyone may be relying on Paul just a little too much.
