Las ventajas de ser invisible

Continuing my journey through the land of banned books. This book is written as a series of letters, and is one-sided correspondence: we only see the letters written by Charlie, the protagonist. This format is unusual and I found it to be engaging. It also means that in addition to describing the action, Charlie is constantly reflecting on it as well, talking not just about the events themselves but also what he perceives as their meaning. Charlie seemed at times to be something of an empty vessel, constantly buffeted by the stronger personalities around him. But the author delivers on why that might be the case.
