Sins of the Heart by Eve Silver — book slip

Dagan Krayl, the Underworld's most powerful soul reaper and demigod son of Sutekh, is on a mission to find his murdered brother's remains and resurrect him.

However, this resurrection could release secrets that might ignite a war threatening both gods and mankind.

Roxy Tam, a Daughter of Aset, is determined to prevent the remains from falling into Sutekh's hands and to stop the soul reapers from reanimating their fallen comrade.

When Roxy encounters Dagan, she realizes they've met before—a meeting that profoundly changed her life.
