Full of thrilling high-octane action, this is the third in an explosive new action-adventure middle grade series.

Perfect for fans of Alex Rider, CHERUB and Mission: Impossible. It's the summer holidays and the S.T.E.A.L.T.H. team is split up. Donna is in the Caribbean visiting family while the boys are bored at home, filling time with computer games - until Sam persuades Arun to pay Donna a surprise visit using MANDROID.

At the same time, plans are underway to hijack and destroy an oil platform off the Trinidad coast while a tropical storm rages.

With MANDROID the only craft capable of operating in such challenging conditions, S.T.E.A.L.T.H. know they have to act to save the workers on the blazing platform and prevent an environmental catastrophe.

Without the backing of MI6, the kids have to go it alone in their most dangerous mission yet... Arun, Donna and Sam are ordinary school kids with an extraordinary secret.

They are S.T.E.A.L.T.H., a crack team of agents in charge of the most cutting-edge piece of tech the world doesn't know exists: MANDROID.

Always flying under the radar, they solve crimes, prevent disasters and rescue the innocent - and they STILL have to get their homework in on time!
