April Henry's latest thriller, In The Blood (Christy Ottaviano Books, 2026) introduces readers to Tessa. Adopted as a newborn, Tessa has always wondered who her biological parents are. After turning eighteen, she takes a DNA test in hopes of finding the answers. With best friend El and lab partner Victor, Tessa uses the results to start building her family tree. But they find more dead ends than answers. Her biological mother, who was raised in a religious cult, has cut all ties with her controlling family. And her biological father remains a complete mystery, at least until the police show up. For fifteen years, they’ve been trying to identify a serial killer known as the Portland Phantom. Tessa may be the link they’ve been waiting for.Learn more about your ad choices.
