Don’t close your eyes. Don’t fall asleep. Don’t let them in.

Thea is an insomniac; she hasn’t slept more than three hours a night for years.

So when an ad for a sleep trial that promises to change her life pops up on her phone, Thea knows this is her last chance at finding any kind of normal life.

Soon Thea’s sleeping for longer than she has in a decade, and awakes feeling transformed. So much so that at first she’s willing to overlook the oddities of the trial – the lack of any phone signal; the way she can’t leave her bedroom without permission; the fact that all her personal possessions are locked away, even her shoes.

But it soon becomes clear that the trial doesn’t just want to help Thea sleep. It wants to control her sleep…

An unputdownable, gripping psychological thriller for fans of The One, Behind Her Eyes and Girl A!

A great debut

Thea, who suffers from insomnia, signs up to participate in a sleep trial after she is involved in a car accident. But this isn’t just any sleep trial and it soon becomes clear to Thea, that this is not a trial to help her sleep, but is one that wants to control her sleep…

When I was offered the chance to read Sleepless, I was immediately drawn to the title as I can relate to this, so I was very interested to see Louise Mumford’s take on sleeplessness. What I got though, was a story so much more than what I and Thea and bargained for!

The plot is original, fresh, well written and researched and really gets under your skin. I was still thinking about this book weeks after I had finished reading it. It just consumes you and you will have a sleepless night racing through the pages to see how it will all unfold!

Thea is an interesting character who I could definitely relate to, although now that I have read this, I will not be participating in any sleep trials in the present or in the future thank you very much! I also absolutely loved Vivian, Thea’s mother, who is a standout and is a big part of what makes this book great.

Sleepless is clever, complex, twisty, unique and a very compelling story. As a debut novel, Louise Mumford has nailed it and I will be interested in reading more of her work going forward. It was a pleasure to read and review Sleepless, which I recommend.
