This is not your average vampire book. Nathaniel Cade has taken a oath to the presidents of the united states. He is their nightmare pet. Cade handles special threats, some that none of us could imagine.Zack Barrows is Cade's handler. Zack is human. The interaction between Zack & Cade is interesting and sometimes makes you just have to laugh.This is the second book in the series and I look forward to the next. When a new outbreak of an ancient evil, one that Cade has seen before - comes to light, he and Zack must track down it's source.Protect and serve often means settling old scores and confronting new betrayals... as only a century old predator can.
