This book immediately transplants you into the world of our main character with beautifully descriptive writing. It's easy to visualise both the surroundings of Ellen, our main character, and the confusion and panic she's feeling at being left with a stranger's child. Within the first 5 pages I was hooked, with the plot rolling out at a perfect pace in which you don't get bored as the mystery is developing and unfolding at a natural speed, rather than one slowed down to make room for unnecessarily lengthy and irrelevant descriptions. Set in modern day London, we see how a woman deprived of her own dream of mothering a child, immediately becomes wary of the dangers of a bustling city as soon as she has a child in her hands. It feels as though she is the perfect choice to be left with the child as a result of her maternal instincts shining through, ready to protect the child at all costs. Obviously this begs the question- was it meant to be her all along?
