This review may contain mild spoilers but will not talk in detail about any important plot points. I bought this book second hand from a used book sale sometime last year and just got around to reading it. The book is about a girl called Emma, who is the last person to see her childhood best friend, Abby, before Abby goes missing. The book is centred around Emma trying to find out what happened to Abby while also trying not to let the unsavoury circumstances in her past (that led to her “abandoning” Abby and moving to a different school) bleed through into her present.
