H.I.V.E.

by Mark Walden

Published 4 September 2006
H.I.V.E. (Higher Institute of Villainous Education) is a top secret school of applied villainy where children with a precocious gift for wrongdoing are sent to develop their talents into criminal mastermind. After all, 'villains have the best lines and wear the best costumes'. One small catch is that the children cannot leave until training is complete, six years later. With villainy comes a certain freedom of thought, and every year one student in particular will show exceptional talent - after all, it takes the best to produce the worst. This year there are two students: Otto Malpense and his new friend Wing Fanchu are both exceptionally bad, and they are definitely not keen on being held against their will for six long years ...

But before they reach their destination, they are ambushed. Who would risk assassinating Otto Malpense, star pupil of the Higher Institute of Villainous Education and favourite of Number One, the most powerful villain alive? A new power is rising to challenge Number One's authority, and they need HIVE and its powerful computer to do so.

Escape Velocity

by Mark Walden

Pupils and staff at HIVE are horrified to discover that Dr Nero has been captured by the forces of HOPE, the Hostile Operative Prosecution Executive, the world's newest and most ruthlessly efficient security force. Three months pass without any news of his fate, and Number One has decided to appoint a sinister new headmistress for the school, somebody that the pupils and staff had thought that they'd seen the last of. Meanwhile Otto is also struggling to cope with new abilities that are starting to manifest themselves; can he really be unconsciously interfacing with computers without physical contact? And if he is, what exactly do these new powers really mean? The only way to find Nero and the truth behind the lies is to escape HIVE. Otto must get out, and take the risks which come with being a rogue agent. Then he just has to break into MI6.

Rogue

by Mark Walden

Published 3 May 2010
The leaders of the world's villainous forces are being picked off one by one in a series of mysterious attacks and Dr Nero is forced to take temporary control of G.L.O.V.E. when Diabolus Darkdoom is seriously injured. He then discovers that Otto, who has now been missing for several months since Dreadnought, is leading the attacks. Under pressure from the remaining members of the ruling council, Nero is left with no choice but to issue a capture or kill order for Otto. Wing learns of the order and persuades Raven to allow him to join her on her mission to retrieve Otto. Other members of the ruling council, suspicious of Nero's relationship with the boy, have initiated their own missions to eliminate Otto. Wing and Raven find themselves in a deadly race against time to track Otto down before the other G.L.O.V.E. assassins get to him. Their pursuit takes them to a secret facility hidden deep within the Amazon rainforest, where they face a mysterious operative even deadlier than Raven. Meanwhile back at H.I.V.E., the school's own automated defence systems turn against the pupils and staff. And there is no one there to stop it.
