"Sutanto has crafted a page-turning work of suspense that questions the line between romantic 'research' and stalking in the age of the internet, analyzing the roles played by abuse, misogyny, racism, and violence in contemporary relationships."—Booklist

"Set against a Northern California private school backdrop, the sensational plot is riddled with twists that come at a furious pace...A suspenseful page-turner."—Kirkus Reviews
