News of a girl going missing near her childhood home transports Felicity back sixteen years to a time when she was a carefree teenager. Carefree, that is, until another girl disappeared, and she fled, knowing more than she cared to let on. Feeling that this is the time to put this behind her once and for all, Felicity is compelled to return to her childhood haunts, using her knowledge of what happened then to help find the girl. Little does she know the full extent of what happened all those years ago and how much danger she is putting herself in by returning…

Having recently read and enjoyed Woman in the Water, the sixth book in the Imogen Grey series, I couldn’t wait to read Katerina Diamond’s latest standalone book, The Heatwave. I was instantly hooked, wondering what it was that happened that had made Felicity leave her home at such a young age, and what it was about the missing girl that had made her go back after all these years.

The Heatwave is told from two perspectives, the first being the aforementioned Felicity, as she returns to Devon to find the truth about the missing girl. It soon becomes apparent that something similar happened years ago, with Felicity fearing that the past has come back to haunt her. It is from the other perspective that we begin to build up the story of what happened as we meet Jasmine, Felicity’s friend, her part of the story being set sixteen years ago, prior to the event that changed their lives forever.

Despite the girls being close friends, they had very different personalities and backgrounds, both of them damaged in their own way. There were many reasons to dislike Felicity and yet, at the same time, I had great sympathy towards her due to the life she was leading. It was easy to see why she was drawn to Jasmine, the girl from the stable home with charity-volunteer parents. All was not what it seemed with Jasmine, however, as we found out more about her past and the troubling time she has had at school.

The arrival of Tim, a lodger at Jasmine’s home, definitely ramped up the tension. It was obvious that he was hiding something but, due to his actions in several different parts of the book, I found it difficult to determine what his motives were. What was he hiding and what was he planning to do?

The Heatwave is a book full of surprises with twists that I did not see coming. The events of sixteen years ago are slowly revealed, the plot becoming much more twisted than I could have ever imagined, with a shocking conclusion that made me gasp several times. I was genuinely taken aback by some of the reveals, some of them sickening and others heartbreaking, and I did not predict any of them!

This is one of those books which draws you in and refuses to let you put it down and I found myself racing through it, desperate to find out what had happened all those years ago. A gripping plot with some very shocking moments, The Heatwave is another great read from Katerina Diamond and I hope that we will see some more standalones soon.
