Veronica Stratton visits her parents for Christmas. She's eager to reconnect with her family, but with the holiday comes a DNA test from her younger sister that confirms her secret suspicions: she's adopted. Having the truth out in the open leaves her feeling unmoored in ways she didn't anticipate. Inspired by her best friend, Veronica plans to go to Europe to see four of the places listed on her DNA ancestry report. She hopes to learn about where her family lived, but she finds that each stop brings her visions of her ancestors that raise more questions than they answer. And among those questions is how Irish castle keeper Niall Callahan will fit into her future.
