The Year Of The Lucy 

Mirelle Martin was a Company Wife — her husband, her children, her home were all held in thrall to the Corporation that owned their lives. She tried — desperately — to conform, hiding the secret of her illegitimacy, her talented father, and her own gifts which might prove embarrassing in a conventional world.
And then came the Year of the Lucy — the year when everything happened, everything big and wonderful and exciting, when Mirelle turned into the woman she had always wanted to be.
