CHERUB 12 : Shadow Wave - Robert Muchamore

The twelfth title in the number one bestselling CHERUB series! James Adams' loyalties are tested in his most dangerous mission yet ... After a tsunami causes massive devastation to a tropical island, its governor sends in the bulldozers to knock down villages, replacing them with luxury hotels. Guarding the corrupt governor's family isn't James Adams' idea of the perfect mission, especially as it's going to be his last as a CHERUB agent.

And then retired colleague Kyle Blueman comes up with an unofficial and highly dangerous plan of his own. James must choose between loyalty to CHERUB, and loyalty to his oldest friend. For official purposes, these children do not exist.
