Katie Collins has barely ever left her tiny Irish village of Ennisbawn. Why would she? With its tightknit community, friendly local pub, surrounded by glistening lakes and perfectly mysterious forests, it’s a place of peaceful beauty. Or it was peaceful. Until Callum Dempsey turned up. Part of a hotshot (and, Katie has to admit, hot is annoyingly apt for him...) development team with zero eye for beauty or charm, he’s not only building a hideous hotel just outside the village, he’s also just announced a plan to knock down Ennisbawn’s only remaining pub.
