Driving Heat by Richard Castle

New York City detective Nikki Heat is at the top of her game — smart, fearless, and fiercely dedicated to her job. But when her own captain is found murdered, everything she’s built begins to unravel.

Teamed once again with journalist Jameson Rook, Nikki dives into a case that cuts too close to home. Every lead exposes another layer of betrayal within the department, and the deeper they dig, the more dangerous it becomes.

As the investigation spirals through the glittering streets and shadowy underworld of Manhattan, Nikki must face her greatest test — uncovering the killer who may be closer than she dares to imagine.
