4Cascadian Intelligence Mission Agent, Zakaya Kalu-better known as "Z"-travels to the United States to visit her mother. But when her young friend, Zeena, sees the men who took her two years earlier and soon disappears, Z vows to find her and bring a ring of human traffickers to justice.

In this sequel to Legacy 627, Z finds herself teamed with, and attracted to, a man she does not entirely trust in order to assist the local police in solving strange murders by a suspect known only as the Kind Killer. By agreeing to assist in this case, Z demands access to evidence in cases she believes will lead to the rescue of Zeena.

Still wanted by the Americans for her part in destroying a dangerous chemical they hoped to weaponize, Z must guard her connection to CIMA and tread carefully as she poses as an ordinary police detective and closes in on the traffickers.

Through it all, Z learns one valuable lesson: No matter who they are or what they have...

Everyone leaves a legacy.
