Did someone steal our embryo? And other mysteries families should not have to solve

A friend asks nosy questions. A daughter remembers a snippet of a long-ago conversation. Old secrets spill out. But "just telling" isn't as easy as it sounds.

Six weeks ago, a woman in her twenties learned that she and her sisters were created through IVF and that she was connected to another person through her paternal line. It's still not entirely clear how that came to be.

In this Q&A, the young woman and her mother tell me about what they know, what they still need to find out, and what troubles them about what comes next.
