BILLY AND BETTY, Twiggs Jameson, Grove, 1968
Alphabetical author-ordering tosses up yet another Grove Press title. Not a lot to say about this one, unfortunately. Its author appears to be a pen-name--or so at least one blogger I discovered maintains, without citing proof--and there are no other books extant under this byline, nor any biographical information.
As for the book itself, it concerns "a futuristic American suburbia, where all life is centered around sex." The little bit of prose I've sampled kinda remind me of the neglected DAD'S NUKE, by Marc Laidlaw.
