Three unsuspecting visitors arrive in a world of magical adventure, only to discover an ancient Thread-wielder has summoned them. For this sorceress, shapeshifter, and soldier, each is destined to play a vital role in restoring peace to the throne of the duke, Aletto, the rightful heir of Zelharri. But secret powers are at work, and for Lialla, the outcast duchess, intrigue and peril finds her at every turn. And while her powers are fierce and fearsome, the magic known as Hell-Light has an uncanny way of determining your fate. What had seemed a time of peace has suddenly erupted into something far more dangerous than any could have foresaw.

The Science of Power

by Ru Emerson

Published 30 January 2013
The spellbinding conclusion to the Night-Threads series begins as a woman of craft, blessed with an overwhelming courage, takes a great risk to combat a traitorous evil that threatens all of Rhadaz. The world remains under the cold-blooded rule of an emperor gone mad, and it is only through the science of power that peace can be restored. But as her family finds the source of their world's many secrets--Chris with the dreaded drug Zero, Robyn finding happiness with Aletto--it is Jennifer's who finds herself readying for one last battle. Whoever holds the power of the sword may just triumph over the devastating power of dark magic.
