Book I

The plane was flying itself. The only person who understood why was the one nobody was watching.

​

When an advanced airliner falls out of a clear New Mexico sky, the wreckage raises a question that doesn't behave like an accident. Allison Tobias designed the system that was supposed to prevent exactly this. She is the first to see that something else was driving. GW Canyon, drawn into the investigation by circumstance and obligation, believes he is at the center of what follows. He is wrong in the way men in this series are reliably wrong — confidently, and a few steps behind the women who actually understand the room.

​

TwinStar is a thriller built on real engineering dread and an unlikely partnership that deepens under pressure neither of them asked for. It is also the first medallion on a charm bracelet five books long — a series in which every story is told through the woman who sees GW Canyon more clearly than he sees himself.

​

TwinStar stands complete on its own. Read it first, or read it alone — the bracelet adds a charm either way.
