“Penance is a rare novel, at once staggering in scope and achingly human. A brutal, white-knuckled tale of betrayal and redemption in which the sins of the fathers are laid upon their children tenfold, O’Shea’s astonishing debut delivers pulse-pounding thrills and the beating heart to match. Fans of Le Carre and Lehane had best take note.”
– Chris F. Holm, Stoker-nominated author of Dead Harvest and The Wrong Goodbye.
“A non-stop adrenaline rush, beginning, middle and end; half Stephen Hunter, half American Tabloid, Daniel O’Shea’s Penance is a bonafide blockbuster.”
– Owen Laukkanen, author of The Professionals.
“Penance has one foot in Bourne and the other in The Untouchables, but tells a very human story of loss and atonement. A great thriller that ranges from the streets of 1970′s Chicago to the highest levels of modern power, with tight dialogue and righteuous violence. One for fans of crime, espionage and mayhem.”
– Jay Stringer, author of Old Gold.
"Penance makes the bulk of cliche-riddled crime fiction sound flat-footed by comparison."
- Peter Farris, author of Last Call for the Living
"A heart-pounding ride that leaves you breathless, yet allows for unforgettable moments of grace. A must-read."
-Hilary Davison, Award-winning author of The Damage Done
"With John Lynch and Penance, Dan O'Shea has produced a worthy competitor [to Michael Connelly]"
"Gritty, intense and exciting."
"Expect PENANCE to shake things up and conquer conspiracy enthusiasts as well as hardboiled literature fans. It's a tremendous novel. The kind you experience, rather than read."
-Dead End Follies
"Penance is a heartbreaking account of love and loss, and the havoc that grief can wreak on an unstable mind."
-Katrina Niidas Holm, CriminalElement
"Pour out yourself a strong glass of Penance, add a couple more fingers worth, and shoot it straight. You might get a fierce burn in the back of your throat and by the time you’ve finally run out, you will be thanking O’Shea for crafting such a rare piece of fine art."
-Liam, The Troubled Scribe
