If you liked The Girl on the Train then I think you'll like this just as much, if not more

What She Left is an extraordinary and bold creation

Every month brings another book billed the new Gone Girl, but we think we've found a winner

A deliciously modern take on the psychological thriller ... a shifting, mesmerising, mysterious story ... very well-written and intelligently realised, occupying a territory half way between literary novel and thriller ... a memorable debut

An absorbing, intricate and extremely original novel. It is also immensely clever and intriguing. It kept making me recall how I'd felt watching Twin Peaks. The kind of immediate shock and grief I felt for Laura Palmer was what I felt for Alice. The process of piecing together the heroine's life is so absorbing. I mourned her more and more powerfully as the story went on. What She Left is beautifully written and very emotionally involving. I hope that it garners all of the commercial and critical success it deserves

There are a million psychological thrillers out there right now, but this one stands out . . . Richmond keeps you guessing until the final pages in this compelling debut

Strikingly modern

A tight, clever, compelling story ... the reader must act as detective, rebuilding Alice Salmon from the digital footprint she leaves behind

A clever, imaginative and entertaining attempt to immerse the whodunit in the world of social media

An ingeniously original premise ... addictive

What a wonderful new voice. What a pleasure to read a thriller that's so ambitious and so full of emotion and suspense. Bravo!

Intriguing and successful ... a crime thriller from a different angle, Richmond's accomplished debut encourages the reader to become the sleuth ... Genuinely chilling

Likely to be one of 2015's most haunting and unforgettable debuts. Accident, murder or suicide? ... A shocking story of love, loss and obsession where everyone has something to hide. It is a great read

Guaranteed to keep you guessing

Brilliant, totally original, "can't-put-down-able"

A classic whodunnit, given a modern twist

An engaging thriller, full of suspense

An exceptional book ... a forensic jigsaw, an ingenious puzzle ... and a most promising debut

Highly original, fascinating and completely compelling. I was hooked on Alice's story from the very first page. A novel guaranteed to make you look back and question your social media footprint, and how accurately it tells your own story

Taut, multi-layered . . . A disturbing, intelligently written novel that's a psychological thriller and crime novel all rolled into one . . . Richmond shatters every assumption with a series of brilliantly delivered curve balls . . . some critics are already comparing it to Gone Girl. They're not wrong . . . the writing is strong, the narrative pace never slackens, while the climax is absolutely blistering

Intriguing ... presents enough believable suspects and motives to keep the reader gripped

This is how books should be written; full of trust and respect for the reader, allowing you to follow the darker paths and investigate yourself. This is a book of immense accomplishment, thrilling and clever - I absolutely devoured it, and I am left thinking simply that none of us are quite what we seem

What She Left leads the reader down a dark and twisty path of suspense and intrigue. This gripping and stylishly written novel left me chilled to the bone and captivated me from beginning to end

WHAT SHE LEFT is bold and inventive storytelling. The reader becomes the investigator, sorting through diary entries, letters, tweets, and emails to discover the truth beneath the tales of an entire cast of potentially unreliable narrators. This is not only a clever thriller, but an insightful exploration of identity and the personae we create in the social-media era

I loved Falling, Emma Kavanagh’s debut novel. With Hidden I feel she has taken it to the next level. Emma Kavanagh is bound to be a leading light in psychological thriller authors. This is gripping, compulsive read. If her next book is half as good as this one it will be a cracking read.

This book is a refreshing take on your traditional thriller. There is no lengthy police investigation after the event - instead, the entire book is devoted to events prior to the shooting. Less a 'who done it' than a 'who's going to do it?' And it works brilliantly, with Emma Kavanagh laying her bait cleverly. Just when you think you've worked everything out, she throws in a bit more information and you realise you're barking up quite the wrong tree. Hidden is a very well-written book, packed with detail yet remaining a book so easy to read that you could devour it in just a few greedy gulps. Dialogue is relevant and characterisation is excellent, making for a most enjoyable, and layered, read.

I think this is the first book I’ve read where the main police character is a Police Firearms Officer rather than a detective. This fresh angle really makes the story stand out, as does the rest of the brilliantly drawn characters and the complex relationships (and hidden secrets) they have with each other. It’s hard to go into detail about this book without giving away spoilers, but what I can say is that it’s a story that keeps you on your toes as a reader. I love books that keep me guessing and challenge me to work out who is responsible, and this story did just that. With several crimes taking place, multiple narrators giving glimpses into different elements of the story, and a super pacey non-linear timeline, the author cleverly ramps up the suspense and the mystery, and kept me guessing right to the end. This is a gritty, tense, twisty page-turner of a book – and a must read for crime and thriller fans.

A second novel is a tricky beast – can the author do it again? Can they build on the success of the first? Can it follow in the same genre without being too much the same?
Kavanagh has succeeded with Hidden when other authors have failed. Similarly to some series on television, the novel starts with the crime and then takes the reader back a stage, to the start of the action. Rather than peeling away the layers to get at ‘who dun it,’ Kavanagh builds up the layers, so that we get to the ‘why’ of ‘who dun it’. Clever stuff, with multiple viewpoints. Kavanagh uses her years of experience training police forces and military units on the psychology of life threatening incidents, to give credence to her work. The tension builds, and never lets up.
Let’s hope there’s another Kavanagh gem soon. Bravo.

The most cunning crime novels, like many of the greatest detectives, trick you into believing you’re smarter than them before pulling out the rug from under you. None more so than Hidden… Kavanagh is certainly deft, batting around the reader like a car with a caught mouse.

It’s clever, complicated and the characters are completely believable….Kavanagh is an original and interesting addition to the genre.
