All-Girl Office by Arthur Adlon

Lena Smith is a she-wolf. Women are her prey, and she has created the perfect hunting grounds – her own consulting firm where the vivacious female employees are “under her” in more ways than one. Lena can’t figure out why a new hire, the strangely assertive Geraldine Powers, makes her heart beat faster. Then she discovers “Gerry” is a preoperative transsexual! If Lena can restore Gerry to manhood, she might make a normal marriage for herself yet.

'In public, Lena boasted that women made better workers. In private, she knew that they made better lovers. Lena Smith was a huntress, and other women were her prey.'
