Zero hour

the long version

"Overlord has been reborn and forced to hop from victim to victim when he erases the personality. Otto is the only person who can contain him, and in order to get close to him, he needs the secret location of H.I.V.E. Nero knows that Otto cannot fall into Overlord's hands, so he activates Zero Hour, a plan to deal with any member of G.L.O.V.E., setting off a desperate race across the globe. But little do they know that Overlord has a new weapon in his arsenal unlike anything they have seen before."--Dust jacket.
