From the back cover:
The groom was having an affair --with his bride's best friend!
Jane had been desperate to stop the wedding. She'd had to prevent her best friend from making the biggest mistake of her life...Marrying Ryan Blair would have been disastrous. He was too rich, too powerful, too hot to handle!
There had been only one solution: to stand up in church and declare that she, Jane Sherwood, respectable businesswoman, was having a secret torrid affair with Ryan! It had worked. The wedding was finished. But now Ryan was determined to make Jane pay for his wrecked marriage--by making her his mistress for real!
