Asylum

CHERUB AU. Oswin is an incredibly bright girl who is renowned in criminal networks for her supreme hacking skills. Despite how well known she is, no one truly knows much about her.
CHERUB agents Amy, Rory and John need Oswin's help to infiltrate the Manchester-based gang, the Daleks. They're trained professionals with one essential advantage: even experienced criminals never suspect that children are spying on them.
But Oswin has a secret that may result in this whole operation going under.
