Young and quiet, Lucy Granger leads an introverted life in Reading, living in a flat and working in design at a graphics company—until it is upended when she both sells her idea for a mobile game and suffers an unexpected medical diagnosis shortly afterwards.
Facing a mandated medical rest period, she decides to use her windfall earnings to take a year's holiday, renting a farm on New Moon Lane in a country village in Yorkshire. As Lucy settles into her holiday home for some tranquility, she soon learns that she is not the only tenant, when a llama named Llarry strolls out of the farm's supposedly-derelict barn. He is shortly followed by others in a menagerie of abandoned animals left behind—from a sickly donkey who likes eating crisps to a flirtatious cockerel sleeping in the back garden.
To Lucy's consternation, no one is willing or able to take them on, leaving her with a strange mix of furry and feathered friends to find homes for. Reluctantly adapting to her circumstances in order to deal with this problem, Lucy will discover other surprises about the animals in her care, and the place she is temporarily calling home. About herself, as well.
Will her ordinary life ever be the same after her experience on New Moon Lane? More importantly, should she really want it to be?
