Something that you don't know is coming or the end that you predict is going to happen doesn't like the ending in My Sisters Keeper.

Has to be an unexpected twist to keep you guessing all the way to the end. And that feeling of wanting to find out, but at the same time not wanting the book to end.

A book you can't put down, a book which keep your heart pounding every time you turn a page.

OMG definitely suspense. It builds the anticipation literally has the reader gripping with anxiousness. They always seem ems to have a brooding character in dark clothing. But it's not those you've got to watch out for its the character yoy would least expect the overly nice try to hard perfect citizens that become the villain. You've got to set the scene carefully delicate with the description an ominous mystery to the air misty atmosphere a dark forest where you here voices whispers in the wind whistling a foggy misty day where you cannot see your hand over your face. Cliffhangers with each chapter. An eerie town where everything seems weird almost quiet something just doesn't feel right but you cannot put you finger on so it niggles away at you until you look more into it investigate look more into. Everything starts to make sense clue clue until someone hinders your progress seems one step ahead at every turn. You start to question you motives who you can trust doubt everyone look over your shoulder.

I think a good thriller needs to be full of twists throwing the reader of the scent. You think one character is involved and then something happens to make you realise it was somebody else, you then work out 'who it is' and again find out you are wrong. The final reveal should surprise you but then make you think, all the clues were there.

Pacy , believable and characters you can relate to. Not too predictable.

Love a good twist! Characters showing their true colours in the last part.

It's got to have something relatable about the main character - if it feels like it's something that could happen to you that makes the tension even more emotive

Good characters, tension and a hint of something in every chapter to keep you turning the page! I also like a twist

A good thriller is when you can't guess who is the culprit until it is revealed

Interesting plot, suspense, the hook and twist from a writer who writes with flow and ease. The king of this has to be Harlan Coben.

A good thriller for me is relatable characters - I like to be able to relate and empathise with the characters. I also like a plot that keeps you guessing til the end - I absolutely detest picking up a new book and being able to guess the ending within the first few chapters - its so predictable and disappointing. I love books - they make me so happy and I love it when a book is a lovely fresh surprise to me.

You must have a good plot, it also has to have twists and turns and usually more than 1 suspect

Believable characters, tension and a plot twist or two

A good thriller keeps is full of suspense to keep you on the edge of your seat, with lots of twists and turns in the plot, it must also allow you to be able to care about the characters

Oh, and when you get to the end, I hate loose ends! Everything has to be resolved, unless the sequel is on the way.....I hate not knowing and 'Grey' endings! A good series for this is 'The No 1 Ladies Detective Agency' series by Alexander McCall Smith.

I like chapters that have cliffhangers towards the end, egging you to read on. Some good books I have read in the past have had chapters written from different character perspectives, which then means you have to read on more than just one chapter, to see what happens to the character in the chapter you have just read. I also like books where the characters are all interlinked, but you have to wait to find out how. Cloudatlas and Ghostwritten, both by DavidMitchell, did this well, though not sure they truly count as thrillers!

A few red herrings and some cliff hangers

Love an unexpected twist...especially in the last couple of pages.

A good story that pieces together and hints on who might be the killer dotted around

A good pace with clues and hints along the way that keep you guessing and then suddenly add up and make sense towards the end when the vital twist towards the end is revealed.

I don't mind the odd twist and turn in the plot, but I object to being deliberately manipulated. Don't spend the whole book making it look the the only possible outcome is one way, and then make it something else in the last chapter. Make events ambiguous, so it's up to the reader to to infer motivations etc.

Pet hate is when a character is made to loom guilty the whole way through, and then suddenly given a pure motive at the end that 'explains' all the times they were AWOL etc.

Any Stephen King book, fantasy but thrilling at the same time. Also like all Stuart Mcbride books

Believable story, lots of twists and turns and characters that you can relate to

A character that you can relate to or feel some connection with. Well written, slowly building up the scenes and suspense with plot twist but not huge daft ones. I love books where you have a snippet of a bit of the book - either the end or middle - so you have some info but you can't really figure it out till later. Or, you think you've figured it out and it then turns out better!
