Raven's Gate

This book is the first installment in the Power of Five series, also known as The Gatekeepers in the US. While it introduces the main character and overarching plot, the subsequent books continue the narrative with new challenges and developments.

Raven's Gate marks a shift for Horowitz into a more overtly supernatural and fantasy-driven narrative compared to his earlier Alex Rider spy thrillers. While both series feature young protagonists in dangerous situations, this book delves into ancient evils and magic rather than espionage.
