You're Next by Gregg Andrew Hurwitz

Mike Wingate, abandoned by his father at four and raised in foster care, is finally living the life he always dreamed of — he’s happily married with a precocious 8-year-old daughter, and his construction company is about to finish a “green” housing development that will secure a solid future for them all. But then something from his own past, a past he doesn’t even remember, comes back to visit terror upon him and his family.

Shady characters begin threatening Mike and, when he reports them, the police seem more interested in Mike’s murky past than in protecting him. Now, with Mike, his wife Annabel and daughter Kat suddenly under attack from all sides, Mike turns to Shep, a dangerous man — and Mike’s only true friend — from his childhood days in foster care. Together they will do whatever it takes to protect Mike’s family against the hidden men behind the terrifying warning, “You’re Next.”
