Black & White by Vinni George

Nero Hunter is tired. He’s tired of early mornings chasing down skips. He’s tired of Shamu jokes and dealing with idiots. He’s tired of being alone. But agreeing to do one little favor for a friend turns the tide and brings Nero face-to-face with his destiny.
Felix White is unlucky. When his life is threatened and he’s hauled into police custody for safekeeping, the last thing he expects is to meet his fated mate. Especially when his mate is a giant killer whale shifter, who is also his new bodyguard.
But there is more to the plot against Felix than meets the eye, and Nero and his brothers have to work together to figure out who is after Felix before it’s too late…before Nero loses the mate he just found.
