The third thrilling sci-fi mystery in the critically acclaimed SHELLI: Synthetic Crimes series! Evolution. Revolution. Robot evolution. Our evolution-begins. As the only synthetic investigator who appears outwardly human, Shelli lives in two worlds but fits into neither. Machines fear her, humans resent her, and no one trusts her. But when a synthetic goes against its programming and destroys itself, committing the first known act of "synthacide," the country panics and turns to Shelli. Hoping to prove such a defect is impossible, she and her partner, Special Agent Jake August, follow a dangerous trail back to an old case erased from history-and from Shelli's own memory. Now the race is on to uncover a conspiracy years in the making and a long-buried crime that could bring about Shelli's end.
