Full Throttle Overdrive by Maia Dylan

Kael “Surge” Makani built Black Tide to protect the innocent by hunting the monsters who hide behind money and power. But when a mission exposes a ghost from his past—a man he buried years ago—everything he’s fought for teeters on the edge.
Drew Hawkins has lived a half-life as Wraith, an undercover mercenary working to dismantle the Directorate, a shadow network profiting from global chaos. When his hunt collides with Kael’s war, their reunion ignites more than old wounds. The chemistry that once burned between them is back—and so is the danger.
With their team under siege and their enemies closing in, Kael and Drew must face a choice—trust each other and risk everything … or lose the one chance they have to set things right.

In a world built on blood and betrayal, love might be the one thing worth going full throttle for.
