I’ve been waiting a long time for a book that blows me away and 56 Days is that book. I genuinely feel quite breathless at how extraordinarily good it is. Absolutely faultless … crime writing perfection.

CL Taylor

Magnificent, even by Catherine Ryan Howard standards. [A] high concept thriller executed with panache and heaps of emotion.

Caz Frear

The queen of high-concept crime fiction.

Jane Casey

[With] this captivating tale … Howard continues to impress.

Publishers Weekly

Another absolute belter from the high priestess of high concepts. Claustrophobic, thrilling and fiendishly clever in both its structure and its twists.

Sarah Hilary

Wow. Original, twisty, and oh so clever – each time I thought I knew what was happening, I was wrong. I loved it!

Andrea Mara

I absolutely loved it. I was sucked in at the start by the brilliant premise and slick writing and then I couldn’t put it down.

Marnie Riches

The lockdown thriller you didn’t know you needed. An utterly brilliant and completely satisfying pageturner.

Catherine Kirwan

At or near the top of any list of superb Irish thriller writers these days is Catherine Ryan Howard. Her fifth stand-alone [is] the masterly 56 Days. Timely, surprising, emotionally alive, this is about as good as suspense fiction gets.

Washington Post

56 Days is a terrific novel written by an author who is certain to become a distinguished voice in crime fiction. You won’t want to stop reading until the very end.

Karin Slaughter

I was surgically attached to this twisting lockdown thriller. Clever, tender and all too convincing, it’s the kind of book you read in one breathless sitting to get to the truth, and then again, slowly, to see how the author did it.

Erin Kelly

[A] terrific, chilling premise, elevated by the plot’s sophisticated architecture. Like a game of Jenga, the chapters pile up with subtle clues and layered twists—until one final piece is revealed, causing everything to come crashing down. This is a first-rate thriller not to be missed.

Sarah Pekkanen for Book of the Month

The Nothing Man was my favourite crime read of last year and 56 Days is even better … mind-blowingly brilliant.

Sue Leonard, Irish Examiner

Anything Catherine Ryan Howard writes will always go straight to the top of my reading pile … 56 Days is her best yet. It’s a spectacular piece of plotting but also a tender, immersive character study that had me completely gripped. ⁣

Phoebe Locke

Catherine Ryan Howard has become my go-to writer for utterly absorbing, original stories with a killer twist and 56 Days delivers all this and more.

56 Days? I read it in 24 HOURS because it was so compulsive, intriguing and fantastically entertaining. I could not let it go.

Liz Nugent

Each new twist, dispensed with surgical precision, will keep you hooked, nostalgic for the days when Covid-19 was the worst threat.

Kirkus

Don’t want to read a lockdown novel? Neither did I. Then I read 56 Days and changed my mind. Absolutely brilliant!

Cass Green

This is likely to be the definitive lockdown thriller. Absolute genius … So many twists and turns, beautifully constructed, great characters and atmosphere.

Mark Edwards

Beautifully written, ingeniously structured, a knockout thriller that doesn’t just encapsulate lockdown but disentangles it. I can’t recommend it enough.

Chris Ewan

Catherine Ryan Howard is one of the best crime writers around.

Sinéad Crowley

Just when I think Catherine’s books can’t get any better, along comes another work of genius. I absolutely devoured 56 Days … It left me guessing up to the end. Brilliant!

Patricia Gibney

56 Days is brilliantly plotted, darkly humorous and utterly unexpected.

Sam Blake

56 Days will engage, it will enthrall, and it will most definitely surprise. Easily one of my favorites for 2021, and one I’ll be recommending to everyone in need of a good book.
