Skeletons of Society (Toxic Paradise, #1) by Marie Maravilla

To survive in the Los Muertos, you have to stay useful. Especially if you’re a woman.

I made sure I couldn’t be replaced. Now they whisper my name in the shadows—La Brujita de Los Muertos—the kingpin’s right hand. They raised me, saved me, and I repay that debt with loyalty soaked in blood. It’s why I've earned the right to run everything in Tucson. Including our newest business deal with the Skeletons of Society MC… too bad that comes with being forced to work alongside the broody, infuriating Sergeant at Arms.
