This was a gripping and twisted thriller that keeps you on edge throughout, with strange occurrences, secrets, and eerie feelings that something isn't right. 
Frankie suffers a great deal of physical and emotional trauma, trying to conceive with her husband Toby, suffering a miscarriage and living in fear after a burglary. When she finds a gated community it seems the answer to her prayers as a place they can build a family in safety. Her new neighbours are friendly, her neighbour's son is caring and supportive while Toby works away, and it seems an idyllic home to raise her family.
But dark secrets lie hidden in this peaceful community, and as Frankie digs deeper she realises she's been pulled into something sinister.
This pacing of this book is great swapping between Frankie and her mother's POV and building up the sense of unease. The final chapters up the pace and reveal tragic secrets, and deadly intentions.
