The Whores of 7th Avenue Paperback

Three women from different worlds and different occupations, come together because of the efforts of a sometimes-mysterious benefactor. In a very short while, they come together like family, all sisters from another mister. It has been a thrill ride full of trials and tribulations, but ultimately all three women are triumphant and go forth to conquer new adventures.
These are the whores of 7th Avenue... Women who sacrificed much to get to where they are.
