It doesn't interest me either because of the sexual connotation and also that threesomes are such a small slice of what is possible with polyamory. It would appear to me to be focused on three-way sexual liaisons, and I would not pick it up to even peruse through it if I were looking for a book on poly in general. Especially since I only conduct my poly relationships one-on-one separate from each other, and have no interest in group sex. But it will appeal to unicorn hunters, I bet. So, if that is who you are trying to attract, then good luck. I have to admit I am surprised that a post with a commercial link in it is still allowed up here. Such posts have had the links removed from them by moderators in the past.
Hot chick in the city.
Oh, oh, can't you see? Love is the drug for me.
