Guardian Angel: Robert Muchamore

Book two of the second CHERUB series, featuring a new cast of characters - just as compelling as the first, which has sold millions of copies world-wide.
Ryan has saved Ethan`s life more than once. Ethan thinks he must be a guardian angel. But Ryan works for CHERUB, a secret organisation with one key advantage: even experienced criminals never suspect that children are spying on them. Ethan`s family runs a billion-dollar criminal empire and Ryan`s job is to destroy it. Can Ryan complete his mission without destroying Ethan as well?
For official purposes, these children do not exist.
