The Promised Land — David Hewson

Bierce was a happily married cop with a bright future. Then on one sunny day in July his wife and their young son were savagely beaten to death and Bierce was convicted of their murders. Languishing on death row a long 23 years later, he still has no memory of the incident. Unexpectedly, inexplicably released just seconds before his execution, he teams up with the beautiful, feisty Alice Loong, who guides him through the confusing new world of the 21st century. But it soon becomes clear that Alice is hiding dark secrets of her own. Pursued by mysterious enemies who are convinced that Bierce knows more than he is telling about his wife's death, the pair are forced into a dangerous race against time to uncover the truth about the events of that fateful day.
