Lexie loves her home. She feels safe and secure in it – and loved, thanks to her boyfriend Tom.

But recently, something’s not been quite right. A book out of place. A wardrobe door left open. A set of keys going missing…

Tom thinks Lexie’s going mad – but then, he’s away more often than he’s at home nowadays, so he wouldn’t understand.

Because Lexie isn’t losing it. She knows there’s someone out there watching her. And, deep down, she knows there’s nothing she can do to make them stop…

Okay, so - wow. I'm not the hugest fan of thrillers, but I couldn't put this one down. I read the first 20% in the evening, then I got up and read the rest of the book over the course of the day - I just couldn't stop! I really liked the alternating point of views of both Lexie and Harriet. I felt like Harriet's chapters came across as quite sinister, even just general day to day chapters, she came across as quite unhinged.. I actually felt quite anxious reading the book, but I just had to know what was going to happen, especially with how the book starts.

Very cleverly written with a fast pace, especially from 75% plus - I'd definitely recommend it.
