His Obsession.

Maude Aberdean has spent sixteen years hunting the kind of men who took her sister and never gave her back. She's fast, she's lethal, and she's spent longer than she'd like to admit believing she works better alone.

Atlas Black has spent his career cleaning up messes his own agency would rather bury, until one mission puts him in a warehouse chasing the exact same case Maude's been building for years, and the two collide over evidence that could finally break the trafficking network wide open.
They should be allies. Instead, they're rivals, competing agencies, competing methods, and a mutual distrust neither of them is in a hurry to let go of. But Atlas can't stop tracking her long after the mission's over, and what starts as reconnaissance stops being about the case a lot faster than he's willing to admit. Maude, for her part, can't quite explain why she hasn't told him to stop.

As the case pulls them deeper into a network more powerful, and more personal, than either of them expected, they'll have to decide how much they're willing to risk. The evidence. Their agencies. Each other.

Some men chase the truth.

Atlas chases her.
