Shortly after he and the Chimera team return from a near-disastrous extraction mission to save a mage in ancient Vienna, the battlefield comes to Windsor Castle.
In the midst of defending the castle, Gabriel is thrust into a wild chase through time to recover a coded notebook that may be the key to saving the Primary Continuum from destruction.
