I looked out the window at the Minneapolis skyline going gold in the late light, and I felt the truth settle over me in slow, heavy waves.

My marriage to Kieran had not been a random coincidence.

My divorce was not the simple end of a tragic romance.

Thirty years before I ever walked into that charity dinner, my father and Alistair Abernathy had stood together outside an accounting office holding a ledger — a partnership, a transaction, an arrangement, something — and whatever had passed between them then had reached forward across three decades to place me, without my knowing it, inside the Abernathy family.

And Alistair, before he died, had understood exactly why, and had written it down, and had sealed it in an envelope with my name on it, to be opened only if his family ever forgot.
