Race the Tide — Mia Maxam

INNOCENT DECEPTION
Christina McIntire had inherited her father's garage business. She was a fine mechanic and worked on the most expensive cars in Florida. It was no wonder that when Scott Kirkner strolled into her garage, he mistook her for a boy.

Deceived by her greasy coveralls, he didn't realize she was a woman--the beautiful woman he would later romance. And at first she encouraged this deception.

Soon, however, she found herself caught in a web of her own weaving. She had fallen in love with Scott! But how could she ever tell this proud man that she had lied to him from the start?
