Shadow Wave — Robert Muchamore

A CHERUB agent must choose between the agency and his own beliefs in the twelfth and final book of the CHERUB series, which Rick Riordan says has “plenty of action.”

After a tsunami causes massive devastation to a tropical island, its governor sends in bulldozers to knock down villages, replacing them with luxury hotels. Guarding the corrupt governor's family isn't James Adams's idea of the perfect mission, especially for his last as a CHERUB agent.

And then retired colleague Kyle Blueman resurfaces with a grudge against the politician that ties back to one of his own CHERUB missions. Kyle has an unofficial and highly dangerous plan of his own -- one that offers him a chance at redemption and James a way to help the people of the island. But can James turn his back on the organization that made him who he is today?
