Chalk Hearts - Emma Whittaker - Bog

Amy escapes her violent boyfriend with a job at Woodbrook Primary School, the place of traumatic memories that still plague her twenty years on.
Secretly ashamed of her loser reputation, Amy hides her ex-pupil status from the staff, even pretending that she has never met Joel, the once-cherished teacher who unexpectedly becomes her colleague.
Under the guise of a confident woman, Amy is determined to eclipse her troubled past. But when she hooks Joel into a deep and passionate relationship, the fear of bursting his bubble with her true identity pushes her ever closer to being exposed.
