Bannon and Vree, brother and sister, they are assassins of the highest
caliber who have long plied their trade for the Havalkeen army. But all
their skill and experience cannot save them from a magic-sprung trap
that will see the two forced to share one body when the very man
they've been sent to assassinate steals Bannon's body for himself. How
long brother and sister can coexist in one body neither can guess. And
so they set out to catch and defeat this foe who has already bested
them once.
But when Bannon and Vree confront this master of a magic beyond
their comprehension, he offers them a terrible choice - to continue
their new dual existence forever, or to betray the Empire they have
served all their lives. For it is not control of Bannon's body which is
Gyhard's true goal but rather the body - and with it the identity and
power - of the Imperial Prince.
