This thrilling quartet of novels will keep you on the edge of your seat as you follow the adventures of Cassandra, the eldest of the Casson siblings, and her brothers Jake and Thomas.

The series starts with "The Name of This Book Is Secret", where the Casson siblings stumble upon a mysterious book with a blank cover and no title page. As they begin to read, they are drawn into a world of espionage, cryptic messages, and mind-bending puzzles. But as they delve deeper, they realize that the book may not be what it seems, and that they are in grave danger.

The series continues with "If You're Reading This, It's Too Late", "This Book Is Not Good for You", and "This Isn't What It Looks Like", each one more twisty and suspenseful than the last. With every new clue and revelation, the stakes are raised and the Casson siblings must use all their wits and cunning to stay one step ahead of their enemies.

This used book in good condition is a collectible treasure for fans of mystery and adventure. With its worn cover and yellowed pages, it's a testament to the many hours spent devouring the series. Whether you're a seasoned fan or just discovering the series, this collection is the perfect way to experience the thrill and excitement of the Secret Series.
