A Death of No Importance. The first in a series, a Death of No Importance is an all-American Downton Abbey….with murder!
Collapse: How Societies Choose to Fail or Succeed. Title says all.

Hidden Valley Road: Inside the Mind of an American Family. The Galvins have twelve children, six with schizophrenia and decades before it was properly recognized in the medical field. Fun fact: Hidden Valley Road is in my parents’ neighborhood.
