An unsuspecting newlywed finds himself the subject of alien scientific study in this humorous tale from the Hugo and Nebula Award-winning author.
After an evening out to dinner, one sultry midsummer eve, Charlie finds himself in the right place at the wrong time: lying underneath an oak tree after making love with his new wife. But while Maria drifts off into dreamland, Charlie finds himself being watched by a one-eyed alien in the branches above.
No leering voyeur is this alien; it's here on research purposes only and has been lucky to observe human copulation. Now it has a favor to ask of Charlie: a personal demonstration. To make the situation more palatable, it transforms into one of Charlie's beautiful ex-girlfriends. To keep the alien's eye from wandering to his sleeping wife, Charlie will have to make the ultimate sacrifice . . .
