Multiple nouns modified by a single adjective phrase -- singular or plural?

I have changed some of the specifics of the following, as technically I’m not allowed to disclose any details of the book I am working on.

I am editing a book and have come across the following sentence:

"The Urban Gothic: A Good Life CD and book are available from channel4.com."

To be clear, the CD and the book are products sold separately; however, the CD is an audio recording of the text of the book, which is itself an adaptation of a single, standalone work.

Should the nouns ‘CD’ and ‘book’ be plural: ‘DVDs’ and ‘books’? Or am I missing another solution to render this sentence grammatical? Or is it grammatical already?

I feel like this is an embarrassingly simple question, but for the life of me I can’t figure it out. Thank you for your help.
