How is it possible to know someone you've never met? With her marriage already in pieces, Joyce Conway nearly lost everything else. But she survived the terrible accident that left her hospitalized—and now, inexplicably, she can remember faces she has never seen, cobblestone Parisian streets she's never visited. A sudden, overwhelming sense of dÉjÀ vu has Joyce feeling as if her life is not her own. Justin Hitchcock's decision to donate blood was the first thing to come straight from his heart in a long time. He chased his ex-wife and daughter from Chicago to London—and now, restless and lonely, he lectures to bored college students in Dublin. But everything is about to change with the arrival of a basket of muffins with a thank-you note enclosed—the first in a series of anonymous presents that will launch Justin into the heart of a mystery . . . and alter two lives forever.
