Investigative reporter Olivia searches for the truth when a mysterious virus that drives people to suicide claims her father. She suspects the virus is a form of germ warfare and joins forces with FBI agent Craig Horn to uncover its secrets. Olivia doesn't trust the government and Craig doesn't trust reporters—not a good situation when she needs him to keep her alive. In Mysterious Circumstances (4), Rita Herron pens a terrifying tale of terrorism and germ warfare that has a very realistic feel. Fast-paced, edge-of-the-seat suspense drives the story from beginning to end.
