Broken Promise (Promise Falls #1)

From Linwood Barclay, the New York Times bestselling author of No Safe House, comes an explosive novel about the disturbing secrets of a quiet small town
 
After his wife's death and losing his job, David Harwood moves back into his childhood home in Promise Falls, New York-where he comes across a shocking family secret.
 
David finds his cousin, Marla, raising a child who is not her own a year after a devastating miscarriage-a baby she claims was a gift from an "angel" left on her porch. When the baby's real mother is found murdered, David can't help wanting to figure out what happened-even if it means proving his cousin's guilt.
 
Marla's mysterious child is just the tip of the iceberg. Other strange things are happening. Animals are found ritually slaughtered. An abandoned Ferris wheel stands as an ominous warning. And someone has decided that the entire town must pay for the sins of its past...
