An Amazon book

I make no recommendations for or against this book, it popped up in an ad while I was looking at a completely unrelated book.

No I wonder if Heinlein is rolling over in his grave or ROFLing in his grave.

The blurb

During a brutal war against monstrous, spider-like aliens, the Space Marines try to improve morale with a top-secret, gene-splicing drug that temporarily turns men into women. Marines who take the drug provide feminine companionship to the Marines who don't. Everyone is happier.
