This is an addictive read. It centres on a block of flats in Central London, in Zone One, where people exist together but rarely make friends with their neighbours and others within the same building, leaving them to live their own lives. It is not the case here.
Harriet and Lexie live next door to each other and the narrative is told by each of them in turn as the story progresses. Harriet is a composer of music for musicals and, on the surface, appears to be successful. Lexie lives with her husband who appears successful in his job and Lexie works from home as a freelance copywriter, which is something she chose to do.
They can hear certain things through the wall between them and Lexie and Harriet become obsessed with each other, always looking up information on the Internet and trying to find out as much as they can about where the other is going and what is happening. They both feel the other has a perfect life but this is definitely not the case.
From one side obsession leads to stalking which is nothing new to this person. There is so much more to the book than this and many topics are dealt with in an interesting and caring manner. I do not want to give anything away.
Thank you to NetGalley, Avon Books UK and Caroline Corcoran for my ARC in return for my honest review.
Highly addictive read and totally recommended.
