Diamonds might be a girl's best friend for some, but for Bread on Arrival bakehouse co-owner Carol MacCallan, her business partners Molly Ferris and Laura Donovan outshine any gem. Long-married Carol is particularly pleased to see a special sparkle in Laura's eyes when they meet Trent McKade, a handsome newcomer settling down in Loch Mallaig, Michigan, after years of travel abroad. Could he be the diamond in the rough Carol's single friend has been looking for? Unfortunately, all that glitters isn't gold, and Trent's connection to the shocking murder of a Bread on Arrival customer clouds the bright future Carol envisions. On the heels of the homicide, Carol's quaint Scottish-themed town becomes overcrowded by mysterious strangers, and the Bakehouse Three are quickly swept up into a multifaceted web of international smuggling, corruption, and assassination. And just when they think the stakes can't get any higher, a hidden menace targets Carol and her family. Stuck between a rock and a hard place, Carol must make difficult decisions about which new friends she should trust--and which ones are enemies in disguise. Can she mine out the truth before it's too late, or will she make a mistake that she'll regret forever?
