Lisa is protective of her daughter, Ava. Maybe over-protective. That’s what Ava thinks anyway. All Ava wants to do is spend time with her friends doing the sort of things other teenage girls do. She has a secret, though, and it is one that spells danger. Lisa, on the other hand, prefers to keep herself to herself, classing Marilyn, a work colleague, as her only friend. Both of these women also have secrets but which of them has a secret so dark that its discovery could change the life of everyone forever?

Sarah Pinborough’s previous book, Behind Her Eyes, was one of last year’s most talked about books, partly due to the #WTFthatending hashtag that was all over social media. It was a book that certainly divided opinion but as someone who really enjoyed it, I was excited to see what Sarah would come up with next.

Lisa and Marilyn are all incredibly flawed characters and it was easy to see how they found themselves drawn towards each other. While Marilyn’s secret is not too difficult to figure out, Lisa’s is truly shocking and not one I saw coming at all. This reveal turned the book on its head and made me question everything I had read. It is hard to say too much without giving away the plot but it is very clever writing from Sarah Pinborough to make you like and loathe a character at the same time.

Ava’s story was probably the one that disturbed me the most as, from the start, there was a sense of foreboding as she communicated with an unknown ‘friend’ on Facebook. Although it was inevitable that this liaison would come to no good, it was not in the way I expected. Another clever piece of writing that, once again, highlights the dangers of social media.

While Cross Her Heart does not make you gasp in the same way as Behind Her Eyes, there are definitely enough twists and turns to keep you guessing due to all of the secrets being kept by the three main protagonists. I loved how the author dropped in a bit of information almost in a blasé fashion, making me wonder if I’d somehow missed a bit of the plot, only for it to be addressed later.

Cross Her Heart is a great read. With thanks to Harper Collins UK and Net Galley for the ARC.
