ooking after his three younger brothers and a Collar-less Shifter who is driving him crazy, but he's putting up with them for Joanne, the human woman he, for some reason, wants to impress. Joanne Greene, while grateful to Broderick for rescuing her sister, doesn't know what to make of him. She's been a loner most of her life, better able to relate to computers and coding than to people, until she's drawn into the world of the Shifters.

Broderick is everything Joanne is not--a fighter and a tracker, from a rough-and-tumble family, better at working with his hands than understanding the netherworld of Joanne's computer programmer life. Broderick is also extremely protective, wanting to draw her under his care as he does everyone else.

When Broderick is captured, mistaken for a Guardian, it's Joanne who figures out that hackers are after the Guardian Network, the database that holds the deep secrets of Shifters past and present. Thought un-hackable, the Network is now in danger of being invaded, and already a Guardian has died. Strangely Broderick now holds the key to stopping the hackers, and Joanne with her coding skills is the only one who can help him.
