Into Shadow — Jane Shoup

How many lives can be destroyed by one man's quest for revenge? A good number, when that man is power-hungry, self-proclaimed king Denyson Folworth. As suspicion mounts that he had his father murdered, circumstances change, control slips, and pressure builds. Folworth, who knows he must change public perception in order to remain in control, will stop at nothing to eliminate his adversaries, especially the renowned assassins known as Forzenay's Five. Forzenay and the others have no intention of allowing Folworth to dictate their paths, but that becomes increasingly difficult as their identities are exposed and a campaign of vicious propaganda gains momentum. Drastic change seems mandated, and difficult choices become the order of the day, but in a deadly game of vengeance, not everyone can or will survive.
