Hannah and Daniel were teenage sweethearts, but then Daniel left their sleepy village of Middlefern and his grandfather's veterinary practice behind for the bright lights of London. Now, 15 years later, the prodigal grandson has returned to temporarily take over the village practice with a veterinary qualification and his dog, Sammy, in tow. Daniel is ready for rabbits with tummy aches, guinea pigs who've lost their squeak, plenty of cow complaints and a whole lot of memories - both good and bad. But is he ready to see Hannah again? Of course, a high-flying city vet like Daniel was never planning to stay in Middlefern for good - especially given his history with the place. But could another, even more important, vacancy convince him to change his mind?
