Blood Test, published in 1986, is the second novel by Jonathan Kellerman. It is told from the first-person point of view of Dr. Alex Delaware, a child psychologist who is Kellerman’s main character in the majority of his novels. …

The novel’s primary plot centers on a 5-year-old boy, Woody Swope, who is gravely ill, whose parents have refused to allow the one treatment that could save his life. …

… Woody disappears from his bed in the hospital …

Though published long ago, I’m astonished how contemporary this book feels.

One of those weird California sex cults is included.
