The Secret Saturdays

Six months after the Kur crisis, the other Secret Scientists have discovered that Zak is Kur, and are tracking him to take him into custody, forcing the Saturdays into a life as fugitives. To make matters worse, the Nagas are also after Zak, in hopes of making him their new leader. Meanwhile, Doyle and Zon go to England and have a run-in with Leonidas Van Rook (who had just had his buisness overtaken by Abbey) when looking for V.V. Argost, who has mysteriously disappeared.
