This is a debut to be reckoned with.

The author conveys a real sense of the true horror of being locked inside a body that won’t move with a brain that still works. And she persuades us to stay with the story to its strangely exhilarating conclusion.

If I Die Before I Wake is a captivating thriller by an exciting new voice. I read it in two days because I had to know who did it! Koch keeps you guessing until the very end.

I loved If I Die Before I Wake. I was completely gripped - a sign of a true story-teller. It's utterly compelling and has an ending that will rip the heart out of you.

A great premise and really beautifully written, with a very moving ending.

A crucial decision in fiction writing is point of view, and Koch, having found a striking angle, makes compelling use of it.

Gripping from the outset and beautifully told, If I Die Before I Wake sucks you in and stays with you long after the final page

One of the most intriguing premises I’ve ever seen in a crime novel… This is a tense, suspenseful novel which slowly builds up into an absolute page turner… this novel definitely establishes Koch’s name as an exciting writer in crime fiction

Now You See Her takes every parents’ worst nightmare and spins it into a tense psychological thriller that’s difficult to put down.’

Gripping from start to finish.

‘With some beautifully engaging dialogue and highly reflective thought processes, the voices of these characters are articulate and carefully crafted. It is swift and engaging to read throughout.’

What a phenomenal, hair-raising, spine tingling, and energetic read this is. My first thought as I finished this book, was ‘one of the best books I have ever read’, but now, I have to say that that has changed now that I have had the time to digest Perks’ outstanding talent. Now You See Her is my most favourite book of all time, my most favourite book of 2018, and Heidi Perks has very quickly become one of my all-time favourite authors.

An amazing read with two sides to it, Charlotte’s side and Harriet’s side, but there is only one truth.

I have a feeling this is going to be one of the most talked about reads this summer. The emphasis is very much on the characters, you will find yourself doubting them, questioning their motives, and desperately turning the pages to get to the truth.

Now You See Her is an absolutely gripping domestic thriller. From the very opening scene in the police station, I was hooked on this story! Brilliantly written and with a fantastic twist, I fully expect this to be a poolside favourite over the summer holiday season.

I read this book in one tension filled evening. I was absolutely gripped by the sympathetic, well-drawn characters and couldn't go to bed until I knew how it ended
