Books by Ritchie Perry

Ever since the terrible murders all those years ago, the Manson house, huge, forbidding and very possibly haunted, had been cloaked in a shroud of mystery and evil. Tom knew he should have put his foot down at Laura's crazy plan, but he couldn't let his own twin sister think he was scared.

By day twelve-year-old Alan Cunningham's a normal school boy. But at night his 'gronk' factor kicks in - and suddenly, he's not exactly your average kind of guy. . . . Now that poor Alan's finally got to grips with the fact that he's a Gronk (a nice, friendly werewolf), a group of mad scientists is after him - to them he's just another experiment.
