When something sounds too good to be true, there has to be a catch, right?A month before Christmas, Nina Tveit finds herself single, jobless, soon-to-be homeless and staring at the computer looking for somewhere she can afford on what little her father left her. She can't believe her eyes when her dream homestead comes up...but it's in Heimli, the newly discovered valley of trolls and other folkloric creatures that most people are afraid of. Christmas is the time of year nisse are most known for, but Nils Jensen plans to spend it alone in his crumbling barn as he has done for the past seventy years. That is until a pretty woman turns up on his doorstep claiming to be the new owner. Not only does she not have the one thing Nils longs for, but she has forgotten the custom of bringing the barn nisse a gift, and he takes it upon himself to make her life a misery. This is the last chance to save the beautiful old farmhouse from collapse, and as much as Nina longs to make it her home, Nils may have pushed her too far. However, leaving the farm might just have dire consequences for the nisse who makes her heart race with more than just anger at his antics. Can Nina fix her mistake and the farmhouse before it all crumbles to dust? Can the magic of Christmas awaken Nils to the opportunity he has hoped for, for so long, that is just within his grasp?
