The Once Upon a Summer series pairs romance with travel, setting each book in a different location during the summer months. Once Upon a Caribbean Summer (1994) and Once Upon an Alaskan Summer (2001) were published years apart, with nearly two decades passing before Once Upon a Montana Summer (2018) and Once Upon an Irish Summer (2020) revived the concept.
Each book features different characters finding love in a vacation setting. The series has a lighter tone than Bergren’s historical fiction and appeals to readers who enjoy location-driven romance.
