Jacob's girlfriend, Rosie, is convinced the man she loves is suffering from stress. But when his moods turn on her, she begins to doubt herself – and she can only hide the bruises for so long.

Books T&Cs apply

For me I like a thriller book which starts right away from the first page with something happening rather than chapter after chapter building up to it.
There is nothing worse than a book that takes ages to get into before something happens

The thriller must have the character who is the baddie in from the start, with many twists and turns. also the characters have to be believable so you feel for them.

a good plot and lots of twists

Sophie Hannah is one of my favourite psychological thriller authors! Her plots are so brilliantly devised and well written, i can rarely guess the outcome! I favour character development over setting descriptions.

I love a plot with lots of twists, one where you can't guess whodunnit & makes you want to carry on reading & not put the book down

Good pacing, a book that keeps you on the edge of your seat and keeps you guessing! :)

Good characters, lots of good sub plots around the main plot and a good late twist that isn't too unbelieveable.

i love thrillers but i love plenty of twists and turns and a good finale

Building suspense that keeps you on the edge of your seat ... I usually get into panic mode!!! lol

A good twist at the end, that has been hinted at but isn't so obvious that you can guess

When it is unpredictable, creepy, dark and full of suspense and the heroin is a character you care about

What I think makes a good thriller are: unpredictability, tension and suspence, a likeable/relatable hero and a small amount of humour

twists, and suspense, so you dont want to put the book down

something that keeps you on the edge of your seat is good

twists in the plot good characters that you care about and that un put able down feeling.

Suspense right to the bitter end - Who Dunnit! Never!

Interesting characters, people that seem normal but have a secret twist. A good plot that keeps you guessing right until the end - and so you have to re-read bits to see why you missed something so simple!

Lots of suspense, and a decent plot twist or two.

well paced, characters that just keep you guessing

a realistic storyline, one where you actually believe 'this could happen' .

A gripping twist, the fear of the unknown and that 'what happens next' thrill

Interesting characters - as long as you love or hate them it doesn't matter

an engaging plot with lots of suspense that keeps you guessing. Plus a twist is always fun :)

i love originality and the constant question of whether the narrator is telling the truth, and i also love when the conclusion is completely unexpected

Not knowing who to trust. I always love a thriller where the narrator is a little unreliable
