Shadow Dance: Book 2 of the Shadows Rising Trilogy

With the discovery of a new lead in Nimkoruguithu, Bren Warring is pulled back into the intrigue surrounding her father's death. After having a chance at a new life on Aethscaul Island, Bren hopes that all she'll have to do is solve another code, but it soon becomes clear that there is much more at stake than finding her father's last binder full of secrets.
When a devastating betrayal nearly costs Bren her life, trust becomes a treacherous commodity, and friends become suspects as the fight to bring the Coventry down moves from the jungle of the Colonies to the ballrooms of high society on the Altyran Coalition continent.
Through it all, Bren must discover just how far she is willing to go to finish what her father started – and how much of herself she is willing to lose.
