Perfect for you if...

You love spy stories with witty banter and genuine friendships at their core, not just gadgets and action sequences.
You've read earlier Spy School books and want to see how Ben handles higher stakes without losing his sense of humour.
You're after middle-grade adventure that respects your intelligence and doesn't talk down to you.

Maybe not for you if...

You prefer standalone stories over series that reward long-term investment in character relationships.
You want grounded, realistic spy craft rather than inventive, over-the-top scenarios played for laughs.
You're looking for romance or adult-oriented plotting in your spy fiction.

About this book

In the ninth book of the Spy School series, Ben Ripley pursues his nemesis Murray Hill on the high seas. Based on evidence from Ben's investigation of the Croatoan, the CIA has located Murray Hill in Central America, boarding The Emperor of the Seas—the world's largest cruise ship—on its maiden voyage around the world. Ben's mission is to pose as a family member alongside Alexander and Catherine Hale as his parents, Erica as his sister, and his best friend Mike as his brother. His goal is to discover what Murray is planning. While a mission aboard the glamorous ocean liner initially seems exciting, complications arise. Ben and his team encounter action, danger, and unexpected obstacles as events unfold.
