500 Miles from You by Jenny Colgan

When Lissa, a nurse who lives in London, witnesses a deliberate hit and run, she can't move on from reliving it over and over in her mind. After it's proposed that Lissa do a job exchange with another nurse, Cormac, that resides in the village of Kirrinfief in Scotland, she agrees. Slowly, Lissa is able to heal and embrace the peacefulness and quirkiness of small town life. By phone and online, she finds herself confiding in Cormac--and he in her. As they develop feelings for each other, they start to look forward to meeting in person. Will their encounter live up to their expectations? 500 Miles from You is the third book in the Scottish Bookshop series.
