Major and Mynah: Operation Raven

Description

When Bo sneaks into Callie’s bag on her school trip to the Tower of London, she and Grace make plans to keep him secret. But when some gold coins and jewels are stolen from the site, having a spy in the sky
comes in useful!
Full of the same humour and mischief as book one, with added history surrounding the Tower of London and the ravens that reside there.
