Movie-making can be murder…

The project
Final Draft, a psychological horror, being filmed at a house deep in a forest, miles from anywhere in the wintry wilds of West Cork.

The lead
Former soap-star Adele Rafferty has stepped in to replace the original actress at the very last minute. She can’t help but hope that this opportunity will be her big break – and she knows she was lucky to get it, after what happened the last time she was on a set.

The problem
Something isn’t quite right about Final Draft. When the strange goings-on in the script start to happen on set too, Adele begins to fear that the real horror lies off the page…

[In] this superior thriller … Howard breathes new life into tired horror tropes.

Publishers Weekly starred review

Catherine Ryan Howard is a master thriller writer and Run Time is up there with the best, as the movie set of nightmares she so evocatively conjures starts to turn on its lead actress. The twisty, ingenious plotting, and the atmospheric location make for a deeply chilling and unputdownable read. I didn’t want it to end!

Catherine Ryan Howard is ridiculously talented.

Chris Whitaker

400 pages fly past … [The] perfect beach read.

Dizzy and dazzling, Run Time offers enough tricks and treats to fill a dozen Halloweens. Movie lovers and thriller fans will devour it.

Riley Sager

A scary, claustrophobic thriller that balances cold creeping tension with cracking wit – Blair Witch meets Fleabag – I laughed out loud then couldn’t switch the light off! A horror about a horror film, set on a set, this is a gem of the genre, delivered with pure mastery.

Pure nerve-shredding suspense from the first page to the last. Once I’d started reading I could. Not. Stop.

At or near the top of any list of superb Irish thriller writers these days is Catherine Ryan Howard.

Washington Post

A perfect holiday read – suspenseful and inventive. Another great high-concept mystery from Catherine Ryan Howard.

Chris Ewan

A book about a movie about a book: Run Time is so, so clever. An ingenious plot, a fly-through-it pace, and along with the creepiness, lots and lots of humour and delicious cultural references. A roller-coaster ride and fun in every sense, I loved it!

Andrea Mara

A ferociously ingenious suspense thriller … [The] structure is brilliantly conceived and meticulously executed … This is a masterful performance, which I read in two sittings; if I’d started earlier in the day, I wouldn’t have put it down.

A story within a story, within a story. Nobody writes thrillers like Catherine Ryan Howard. I was hooked from the first page. An original, clever and unputdownable thriller. I loved it!

A mind-twisting story about the filming of a horror movie. Compelling doesn’t do it justice, this book is flat-out addictive. Catherine Ryan Howard never fails to write something that’s inventive, creative, and captivating

Twisty, claustrophobic and totally unpredictable.

Twisty, clever, complex, blackly comic and, oh yes, skin-crawlingly scary.
