Lee Raven, boy thief, has stolen something he really didn't mean to.

Now he faces a perilous flight through London (and the murky sewers below) as he tries to escape capture – because Lee has stolen the Book of Nebo, a book that has existed for thousands of years and tells every story and legend known to man. It's priceless. Some will even kill to possess it. The pressure mounts and the future of Nebo is in Lee's hands – can he prevent the most dangerous ending of them all?

Praise for Zizou Corder and the Lionboy trilogy:

'A new star has appeared on the children's literary firmament' – Independent

'One of the best books of the year' – Mail on Sunday

'Stunning' – Observer

'Simply absolutely brilliant' – Disney's Big Time

Zizou Corder is the not-so-secret identity of Louisa Young and Isabel Adomakoh Young, who have been writing together since Isabel was seven. They have written three books together: the Lionboy trilogy. They wander the world in a large blue canoe, and have 17 pet ducks as well as the lizard and the dead tortoise.
