What Makes a Good Spine-Chiller?

As the name suggests, Thriller Books are written to provide thrills. A good author will be adept at building tension and suspenseful excitement punctuated with elements of surprise, to keep you on the edge of your seat. It is the suspense factor that keeps the reader engrossed and wanting more until the story climax. It's what make's thriller fiction on obooko unputdownable.

Thrillers are about suspense and nail-biting excitement, often featuring an innocent person being hunted by someone who wants to kill them or someone who witnesses a criminal act and needs to disappear before they can tell anyone what they saw. Mystery thrillers often have lots of action scenes with car chases, shoot-outs and explosions that keep readers on their toes as they try to figure out how everything will turn out in the end.

The psychological thriller books in this collection are written to build excitement while heightening the reader's anticipation and anxiety right up until the story reaches its culmination. Often, key elements that would help the reader solve or reveal aspects of the plot are deliberately hidden or withheld in order to confuse; or left in full view to distract and mislead by using literary devices like a Red Herring or the device popularised by Alfred Hitchcock, the MacGuffin.

Many thrillers can also be categorized as Crime novels. Stories in this sub-genre take place in modern times, but others take place in historical settings or even futuristic worlds. These novels often feature characters trying to solve a mystery or catch a criminal, so they're perfect if you like reading about detectives solving cases.

Mystery Books Explained

Mystery Books and novels are different because they are written in a style that engages the reader in a way that they become much more than an observer: they assume part of the investigative component of the story; trying to figure out from the facts, who committed the crime or offence. The author will use a variety of plot techniques and devices, many similar to those used in thrillers, but with more emphasis on concealing the identity of the perpetrator or concealing facets of a felony in order to keep the reader guessing. The primary character is usually a detective or private eye, who in order to solve the mystery, compiles a list of suspects likely to have motive and opportunity.

In the best mystery books there does not have to be a crime: the protagonist is tasked to find the reason why something has occurred, as in supernatural mysteries. Many of the stories in our Action & Adventure category contain elements of thriller and mystery, so make sure you head over and check them out.

There are many types of mystery books, which focus on solving a case through logic and reasoning; locked room mysteries, where one or more murders occur in a room locked from the inside; and historical mysteries, which focus on solving crimes from long ago.

Full of suspense and intrigue, with a little bit of detection thrown in for good measure (and perhaps a love interest), detective mystery books are perfect for readers who like to get lost in a gripping story with plenty of twists and turns. The best way to enjoy these ebooks is by reading them on your dedicated e-reader, phone or tablet, where you can keep a close eye on how quickly you're consuming the book and how many pages you have left to read. And bookmark where you left off.

Some of our Free Mystery Books:

In mystery fiction there are many types of sub-genre, including detective stories, which focus on solving a case through logic and reasoning; locked room mysteries, where one or more murders occur in a room locked from the inside; and historical mysteries, which focus on solving mysteries from long ago. And a cross-over subgenre know as mystery thriller books.

Usually set in small towns, cozy mysteries are where everyone knows everyone else and a friendly group of amateur sleuths gather together to solve local lawnessness. In this subgenre, the murder is often gruesome and shocking, but not explicitly described.

The subgenre of police procedurals covers detective stories about homicide cops or forensic scientists solving crimes using clues found at the murder scene or by analyzing DNA evidence. These stories can be serious or humorous depending on the author's style.
