Tainted Realm is the new adult fantasy trilogy mentioned previously, essentially unrelated to the Three World saga.
Twelve years ago, two children witnessed a murder that still haunts them as adults.
Tali, a slave girl in subterranean Cython, saw her mother's head hacked open and something taken from inside. Rix, boy heir to the biggest fortune in Hightspall, watched two shrouded figures do the deed. He did not realise they were his parents, acting for a faceless sorcerer.
Tali has sworn to bring her mother's murderers to justice, but now she is hunted by a killer who can only be beaten by magic - Tali's magic that she does not understand.
Her dramatic escape precipitates Cython's war on a weak and unready Hightspall. Tali meets Rix by chance and they flee through a land in turmoil, hunted by enemies and allies alike. But before they can solve the crime, and save the realm, Tali and Rix must learn to trust each other.
The rebellion is led by Lyf, the embittered wraith of a long-dead Cythonian king whose sorcery has brought Hightspall to its knees. To restore himself to life Lyf needs only one thing - the master pearl his magic has cultured inside Tali's head - and he is determined to take it.
As she unravels the conspiracy behind her mother's murder, Tali's quest for justice turns to a lust for vengeance. Unfortunately, only one person can teach her how to use her unruly magic - Lyf himself.
