According to Ted White, e*I*26- (Vol. 5 No. 3) June 2006:
“In eI25, Lynn Monroe says, ‘Or Dean Koontz, who is in heavy-duty denial about the 30 porno titles he wrote with his wife 36 years ago. Dean has successfully re-invented himself, and I sincerely believe that he sincerely means it when he swears he did not write those books, because I believe he thinks that 1970 Dean Koontz was a different person. Too bad they accidentally put his real name on Bounce Girl.’
“As a matter of fact, they ‘accidentally’ included his wife’s name as well. The byline was ‘By Dean & Gerda Koontz.’
“How do I know this? Because Dean sent me a copy when it was published, and inscribed it to me! At the time (late ‘60s) he was very proud of that book.”

According to Dean:
“In 1969, Dean agreed to have a small publisher publish two of his non-fiction works (one entitled THE SICK SOCIETY and the other entitled GOING UNDERGROUND) and two of his fiction works (one entitled HUNG and the other entitled TIGER 650). All four books were presented to the publisher as finished manuscripts and Dean fully expected for them to be published in the form submitted to the publisher. Unfortunately, all four books were put into production before Dean learned that the publisher had arranged, without Dean’s knowledge or consent, for them to be so completely rewritten that none of them, as published, bore much resemblance to the original manuscripts as submitted by Dean. Although he wasn’t able to stop publication, he did get the publisher to contractually agree to publish all four books under a pseudonym. The publisher further agreed to indemnify Dean against claims arising from the material added by the publisher: “Author and Publisher acknowledge that…the Work will be published with material changes from the original manuscripts of same, that the Publisher assumes all liability for the content of those new chapters and passages.” However, only one of the four books was published under a pen name- HUNG was published under the pen name Leonard Chris. THE SICK SOCIETY manuscript was published under the title PIG SOCIETY, the GOING UNDERGROUND manuscript was published under the title THE UNDERGROUND LIFESTYLES HANDBOOK, and the TIGER 650 manuscript was published under the title BOUNCE GIRL- all with Dean and Gerda Koontz as the credited authors, and therefore in breach of Dean’s contract with the publisher. Copyright Office files on all four of these books now reflects affidavits from Gerda and Dean stating that (1) Gerda did not participate in writing any portion of these books and (2) Dean disavows any claim of authorship or responsibility for the content of these four books due to the substantial nature of the unauthorized changes to his original manuscripts.”
