Plot
Alexa Daley, the protagonist, had only recently defeated the Abaddon (the main antagonist throughout the series)...or so she thought.
Abaddon was last seen falling back into the black pit in which he was contained, defeated along with Victor Grindall, one of Abaddon's underlings. Abaddon had taken on a new form, a metal serpent of the sea, harnessing the deadly power of electricity.
