Sylvia Blackwell, a young woman in her twenties, moves to East Mole, a quaint market town in middle England, to start a new job as a children's librarian. But the apparently pleasant town is not all it seems. Sylvia falls in love with an older man - but it's her connection to his precocious young daughter and her neighbours' son which will change her life and put them, the library and her job under threat.
