NY, Putnam's, (1988). One of his first books to be published by a mainstream publisher -- after selling some 40 million books worldwide that were done by paperback or specialty publishers. Inscribed by Koontz with a warm personal inscription: "To ___ - This tale of a guardian angel with a dark side - from a writer with no dark side of his own. (Did you buy that)? As ever, Dean R. Koontz," with a drawing of a lightning bolt above the signature. Together with an autograph letter signed, one full page, transmitting the book and then commenting on a number of things: "When I wrote it, I worried that it was too complicated and wild for the broader mainstream audience. Putnam's was certain of that! But it turns out to be right down their alley, with almost 200,000 in print after only five weeks, which is further proof that publishers often underestimate the reading public's IQ." He also compliments the recipient on a "terrific interview with [Whitley] Strieber" in a recent magazine: "His answers were astonishing at times and perhaps unintentionally illuminating. Great stuff." Signed "Dean." Owner bookplate (designed by fantasy artist Gahan Wilson) on the front flyleaf, otherwise fine in a fine dust jacket; the letter is also fine. [#032796] SOLD
