It Started with a Book by Camilla Isley

When she’s ghosted by yet another Tinder match, Leighton swears off dating for life. Who needs apps and blind dates when she has the perfect-in-every-way (apart from being fictional) heroes of her beloved romance novels?
That night, Leigh finds a second-hand book on her TBR pile that transports her to the small-town of Lakeville Hills, where the heroines wear shorty-shorts and the men drink bourbon. And as Leigh drifts off to sleep, she dreams of billionaire cowboy Killian St Clair, who could win a gold medal for smouldering and bicep flexing.
For a while, Leigh finds it easier to stomach misogynistic supervisors, newly coupled friends, and extravagant bridesmaid duties knowing she can return to Lakeville Hills each evening. Until one day she wakes up to find she’s brought a bit of Lakeville Hills back with her: the impossibly sexy and entirely implausible Killian St Clair is in her apartment.
Now Leigh must help Killian navigate the real world. But as she gets to know the man behind the trope, can she keep her heart safe, or does she risk falling in love with her book boyfriend in real life?
