“This book hits the ground running and never loses speed. I absolutely loved the premise of this story, and the way the story flows and the plot develops so naturally is a treat.”

– Thomas, @city.of.paper.and.ink

“The plot itself is propulsive, and I found myself flying through this story… This book is gritty and really dives deep into the psyche of sociopaths and serial killers. And what an ending!”

– Toya, @thereadingchemist

“I think None Shall Sleep is a stellar psychological thriller, and I’ve already recommended it to so many people. Especially for the YA thriller genre, this is peak literature and one of my new favorites.”

– Alexia, @BookishEnds

“The characters in None Shall Sleep are masterly developed and maintained. The amount of research and thought that Ellie Marney put into these personas is phenomenal. Emma jumps off the page for the reader. Her struggles and thought process absorb you. Simon is chilling and thrilling while also providing a charismatic bait you want to resist. You get nervous as you read the development. You know things will be glorious and terrifying but you can’t look away.”

– Ash, @ashesofabookdragon

“This is, without a doubt, one of my favorite books of all time. Everything from the writing to the characters to the plot development drew me in and refused to let me go. Let’s just say that Ellie Marney has a fan for life, no matter what genre she dives into next.”

– Madison, @spellbindingstories

“Absolutely loved this book! There is going to be a second one and I cannot wait… This might be one of my all time favorite murder/thriller books.”
