Blood Men by Paul Cleave
Mixed takes from PW & Booklist, so I'll list 'em both for your discernment:
From Publishers Weekly
New Zealander Cleave's disappointing U.S. debut focuses on the son of a notorious serial killer. When Edward Hunter was nine, his father, Jack (aka "Jack the Hunter"), was convicted of murdering 11 prostitutes in Christchurch, New Zealand. In the 20 years of Jack's incarceration, Edward hasn't spoken to or visited him once. Edward is doing okay in his struggle to get over his past until the day shortly before Christmas he and his wife, Jodie, get caught in the middle of a violent bank heist that leaves Jodie dead. Edward, who has always feared that he'll turn out like his father, is shocked when Jack contacts him from prison and encourages him to seek revenge on the robbers. He's even more shocked when he takes Jack's advice. While Cleave (The Cleaner) explores intriguing concepts-- particularly the gray area between guilt and innocence--and the steady stream of blood never feels gratuitous, too many subplots and character motivations compete for anything to truly resonate.

From Booklist
What was it like to grow up with a serial killer as a father? Edward Hunter knows: his father has a monster inside him, and although he's now in prison, his legacy is something Edward has always feared. But Edward is nothing like his father. He has a good life—friends, a job, a loving wife, and a child he adores. All that changes though, the moment he calls out to save a bank teller from being killed during a hold-up, and the robbers kill his wife instead. What has he done? How can he fix it? When the police work too slowly, Edward decides to investigate himself, and as he does, he connects with feelings he has denied his whole life—and discovers his own terrible monster. Compelling, dark, and perfectly paced, New Zealand writer Cleave's psychological thriller explores the evil lurking in us all, working relentless magic until the very last page. There's nary a misstep in this riveting thriller about the bad deeds even good men sometimes do. --Stephanie Zvirin
