For You I Will by Hadley Raydeen

Callie Johnson is used to running the show as the office manager at Harmon and Associates, a top law firm in the city. She runs the office smoothly and without being second-guessed. She likes it that way, having all the control. The managing named partner, Paul Harmon trusted her to take care of the office while he tended to the law.

When Paul takes a leave of absence, due to health reasons, he leaves his duties to his protégé, Daniel Morrow. The definition of control, he and Callie bump heads over decisions in the office.

The two should be considered equals, but Daniel seems to like to throw his weight around.
When the firm gets bad news, Daniel and Callie must work together to keep the firm going or it will be ripped out from under them both. Can they find a way to work together when circumstances, and the person you work closely with, makes you re-evaluate the need for control?
