A pulpy gem ... Haas' kinetic prose moves this fast-paced story right along and makes it the escapist fun to while away a holiday afternoon."

"A fine and riveting pick for mystery-thriller readers."

"When push comes to shove, the bullets don't just fly. They find their targets."
--- New Jersey Star Ledger, on Dark Men
"Columbus is absolutely one of the best reads I've had this year. ...Haas is a guy whose work I'll pick up any time he publishes. He's that strong a writer, and Columbus is that strong a book."
--- Drew McWeeny, HitFix.com, on Columbus
"Tight, swift debut thriller... reminiscent of The Manchurian Candidate. By telling the story from the assassin's point of view, Haas layers on novelistic texture. In chilling interior passages echoing The Day of the Jackal, the 'bear' explicates the cold-blooded methods that make him a top killer. All the while, Haas stokes sympathy for his anti-hero. Lean work, with every word counting and adding up to more than most authors land in twice the space."
