She is also the best engineer of her generation — and when Ronan Callahan, the man she has sworn to destroy, offers her chief-engineer-of-Kestrel money, she takes the job for one reason: to watch him lose.

Ronan Callahan has been reading her dissertation since 2022. He built her team. He hired her chief mechanic, her sim engineer, and the wind tunnel she would one day demand. He wrote she is the smartest person I have ever read on the back page of her thesis four years before he ever shook her hand.
He has, also, been keeping a secret about her father for nine years. A secret her father made him swear, on the morning of the day he died, that he would never tell her.
The promise had three parts. Two of them are about to break.
One season. One impossible affair. One forty-one-second voicemail in a Charleston kitchen that is going to detonate the only family Sloane has left.
