Dearly Beloved (A Match Made in Heaven #1)
Peggy Jaeger

Playboy Slade Harrington doesn't believe in marriage. His father's six weddings have taught him life is better as an unencumbered single guy. But Slade loves his little sister. He'll do anything for her, including footing the bill for her dream wedding. He doesn't plan on losing his heart to a smart-mouthed, gorgeous wedding planner, though.
When her ex-fiancé comes back into the picture, Colleen must choose between Mr. Right and Mr. Right Now.
