"'When did you last Google yourself?' Wealthy businessman Will Frost, gets woken in the middle of the night by an anonymous caller, asking him exactly this. When Will goes online, he finds a website has been set up in his name, showing photographs of the inside of his home, along with [photographs] of six houses he's never seen before. In the first of these strange houses, a gruesome murder has already taken place. Will is then told that his own family is in mortal danger. The only way he can keep them safe is to visit each of the houses on the website in person-- before the police discover what has happened there. Seven houses. Seven gruesome homicides. Seven chances to save his daughter's life."--P. [4] of cover.
