The Serial Killer’s Party by Amy Cunningham: The review

If there’s one thing media has taught me over the years, it’s that no good ever comes from attending a rich people party. Nothing. And The Serial Killer’s Party takes that idea and turns it up to 11 by throwing us into a three-day party with death and debauchery galore. I’m glad I’m not a guest, but by god, I’ve absolutely loved reading about it. 

The Serial Killer’s Party follows Amelia, a young woman who has been searching for her sister who went missing after attending the annual party of Lawrence Fowley in his huge estate in Norway. The police don’t care; they think she’s simply off travelling, with no real sign she’s missing or in danger. But Amelia knows her sister. She knows something is wrong. Amelia has had to take extreme measures to do so, but she has managed to get herself access to the Fowley party the following year. She isn’t leaving without answers, but it’s not until she’s there that she realises quite how much danger she’s put herself in.

It seems her sister isn’t the first, or last, person to mysteriously vanish or die after attending one of Lawrence’s parties. As dangerous as the host seems, however, his brother James is equally shady. This isn’t a family you want to mess with, but Amelia has lots of snooping to do if she wants to find answers.

Cunningham wastes no time in throwing us almost straight into the action and, for the entirety of the book, this is a non-stop rollercoaster ride that will have you on the edge of your seat. The tension is palpable as Amelia sneaks around the estate, and every encounter with the Fowleys will leave you on the edge of your seat. I absolutely loved reading The Serial Killer’s Party; it has atmosphere in droves and the pacing is perfect in the way that it’s fast enough to keep you hooked, but beautifully descriptive that it feels like you’re right there. Whether Cunningham is describing the Fowley mansion, or the sprawling Norweigan forests that surround it, it’s wonderfully told with just the right amount of detail to keep us completely absorbed in the story.

Get this book on your tbr immediately if you love tense thrillers. Oh, it’s twisty too: that ending threw me for six! Absolutely loved it.

With thanks to Random Things Tours and Penguin for providing a copy of the book in exchange for my honest review.
