The blood of "carriers" is the most valuable commodity on earth. When treated with a new wonder drug, it cures disease, increases power, and makes the recipient a virtual superman.

It also makes the carriers targets. Young people with the right genes are ripped from their families and stashed in "blood farms."

Ellie Batista became an LAPD officer specifically to fight this evil as a member of the Blood Squad, but her ambitions are thwarted--until the day she and her partner are ambushed during a routine stop. The resulting events plunge her into an undercover world more dangerous than she could have ever imagined.

Because a madman has found a way to increase the potency of the blood to levels previously unimagined. As he cuts a bloody swath through the already deadly world of blood cartels, Ellie is the only hope to stop him before the body count explodes.
