What’s it about?

The story.

Sophie and Sienna are on the Dorset coast, enjoying a week of sailing in the summer sunshine, when an unexpected message throws them onto the trail of a gang of kidnappers. Their search leads them to a medieval castle and an eerie, mystery-shrouded lighthouse, and as storm clouds gather the girls find themselves in far more danger than they realise. And if Old Tom is right, and the Beast of Abbot's Wood really has returned, then surviving a battle with the kidnappers may be the least of their problems. The fifth book in A.B. Martin's Sophie Watson series pairs a coastal, storm-lashed setting with the series' reliable blend of chases, twists and a creeping legend, told at a brisk, filmic pace with short cliffhanger chapters. It suits confident 9-13 readers who like their adventure-mysteries fast, atmospheric and high-stakes, and reads well aloud to slightly younger listeners who enjoy a shiver.

Fit check

Right for your child?

Where it lands by age

Best fit is confident 9-13s reading independently, drawn by the storm-coast atmosphere and fast pace. It reads aloud from about 8 for children who enjoy a shiver, though the peril makes it less of a bedtime pick. Little adult crossover.

About the author

A.B. Martin.

AM

A.B. Martin

Writer · United Kingdom

A.B. Martin is an English author of fast, cinematic adventure-mysteries for confident 9–13 readers, best known for the self-published Sophie Watson series. Across six books, from Kestrel Island through Under Crook's Wood, Raven's Wharf, Silver's Gold, Dion's Shadow and Arator's Secret, cautious schoolgirl Sophie and her bold friend Sienna are pulled into globe-threatening plots, chasing stolen relics and buried secrets through seaside towns, wintry London and Roman ruins. Before turning to fiction, Martin wrote for television and radio and performed comedy at venues including the London Palladium, and that stagecraft shows in the brisk, filmic pacing, short cliffhanger chapters and relentless momentum. He lives in London. A dependable pick for reluctant readers who want jeopardy, chases and secrets on every page, without content that tips into genuine horror.
