It all began as just a little landscaping. Lily Pierce dreams of magnolias blooming next to her front porch. But nothing seems to be easy for Lily especially when she digs up a mystery in her very own yard. That magnolia tree may never find a home!

Devlin Pierce is beginning to worry. His post-it note loving, list making wife seems to discover a dangerous adventure around every corner, but this one is too close to home. When the mystery is planted in Dev's past and could threaten his family's future, he calls upon his old friends to reunite for another mission-to look over the woman who just can't walk away from a good mystery. For her husband, it's becoming a major dilemma, but he'll do anything for the woman he loves.

The welcome mat is out for danger, and a mystery is knocking on Lily's door! Again!
