Kill Monster Sean Doolittle Livres

A golem created to assassinate a criminal in 1856 is reawakened 150 years later. With the original target long since dead, it sets its sight on the man's closest surviving descendant... burned out IT technician Ben Middleton. Ben must pull himself together to not only save himself, but also his estranged teenage son Charley.

Seven friends, one eccentric billionaire, and an all-expenses-paid reunion on a private island: with no technology allowed, it'll be a weekend to remember- for those who make it out alive.
