The Black Guard: Evolution: Black Guard Series, Book 2 (Unabridged‪)‬

Dragon Sapir is back, and the Jax Military will never be the same.

The Jax Contract Committee, JCC, has released Rivka to take assignments, and her first involves her in a plot by several Systems within the Helix collection of systems to destroy the Jax. As the plot spreads, she is given assignments to combat the threat. Soon she becomes the JCC's problem solver for ill-advised and potentially ruinous contracts the JCC is forced to accept, including one by the United Freelands who is seeking revenge on her for their embarrassing defeat on Suryah.

Rivka has become the agent of change, an essential evolution if the Jax is to survive.
