Douglas Hartwell
The vanishing man. A garage. A question.
Forty. Hotel networks. Ordinary on purpose. Then the machine in the garage stopped being a hobby.
By day, Douglas Hartwell keeps hotel networks running and pays his bills. By night, in a suburban garage, he builds a machine from copper wire, salvaged cooling parts, and a question he can't let go: what if reality, as he knows it, is only one station on a dial?
The experiment doesn't stay in the garage. It leads him to Travelers, to a planet that heals, to Elowyn, and to the Thren. And at the far end of all that sky waits a ranch in Colorado, a copper ring, and a life he is certain he got right.
Douglas isn't a side chapter in the Billy Thinx story. He is the hero of Between Lives.
