The Nanny's Secret, The Wife's Revenge

The call came from my son's elite private school. The nurse was cheerful, telling me seven-year-old Jace had a minor scrape and needed a routine blood transfusion.

Then she said something that made my blood run cold. "It's a good thing we have his A-positive blood type on file."

My husband, Christian, and I are both O-negative. It's biologically impossible.

A secret DNA test confirmed the horrifying truth. Jace was not my son. He was Christian's child with our live-in nanny, Kassidy.
