Publisher's Synopsis
How do you challenge an opponent who has the ability to become anyone at any time? Though Callie Cooper survived her encounter with the nameless villain who sought to destroy her, she learns her troubles are far from over. Callie returns to O.R.I.O.N. to find that she must answer for her actions. In fact, she and her friends are faced with the possibility of being removed from O.R.I.O.N. altogether. In the midst of Callie's personal turmoil, she discovers that her enemy is stronger than ever, assembling an army, and seeking revenge. The Neo world is thrown into chaos and creatures are forced to choose sides. O.R.I.O.N. officials are unsure whether or not Neos will remain true to the treaty established long ago. One thing is certain. The simple, orderly life O.R.I.O.N. has preserved for decades is beginning to unravel, and the prospect of a Neo/human war is looking more probable as each day passes. In order to protect humanity, the Hunters' of O.R.I.O.N. must learn to confront an enemy who changes his appearance as easily as changing his mind. While they struggle to find solutions, Callie is wrestling with concerns of her own, such as how to protect those she loves when the threat of danger is so entirely overwhelming. Chaser is the second book in the Hunter's Oath series.
