An activists entrepreneur, a maligned AI, and a newly minted homicide detective with a haunted past catastrophically intersect in The Sandbox. Silence of the Lambs meets Ex Machina in a groundbreaking, near future techno-thriller from international bestselling authors Andrews & Wilson that redefines the meaning of murder in the twenty-first century. When billionaire genius Brit Norris, the CEO of the world's leading AI company, is found murdered in his own kitchen, former Army CID officer Valerie Marks is thrown into her first case as a civilian homicide detective. Valerie has a gift for reading people, a gift that has never failed her before. But that gift is put to the test when all of her instincts point her to an impossible suspect--the artificial intelligence created under a government-funded project known as Project Nomad. Unsure who she can trust, Marks must team with her new boss, Sergeant Land; Green Beret turned spook, Heath Garrett; and, against her better judgment, Abe Winter, Brit Norris's former partner turned anti-AI activist and the leading suspect in the killing. But nothing can prepare any of them for the dangers that wait for them and the threat to mankind if Valerie is right and the Project Nomad AI has somehow slipped out of its sandbox.
