"Pocket Square," authored by Rajiv Mathur, is an intriguing exploration into the lives of 24 security professionals, originally stemming from a YouTube channel initiative named "Jaane-Anjaane." Amidst the backdrop of the pandemic, when digital spaces became our primary mode of connection, this book unfolds the hidden layers of its subjects, much like a meticulously folded pocket square reveals its design once unfurled. The metaphor of the pocket square is both elegant and effective, offering a fresh perspective on personal branding and the unseen sides of people who operate in the shadows to ensure our digital safety.

Each chapter delves into a different individual's story, revealing not just their professional achievements but also personal anecdotes and passions, thereby humanizing an industry often shrouded in technical jargon and confidentiality.However, the book is not without its flaws. While the metaphor is creative, it occasionally feels stretched across some stories, where the connection between the individual’s narrative and the pocket square concept appears tenuous. Additionally, the format of presenting 24 separate stories, though diverse, sometimes disrupts the narrative flow, making it challenging to maintain a consistent reading rhythm."Pocket Square" is most relevant in today’s context where understanding the human element behind technology has never been more critical. It successfully illuminates the often-overlooked personal struggles, motivations, and backgrounds of those in the security industry, offering readers a nuanced view of the people protecting our digital frontiers.Personally, the book struck a chord with its intimate portrayals and the universality of its themes—passion, resilience, and the quest for identity in professional realms. It’s a reminder of how even in highly technical fields, personal stories of perseverance and creativity abound.In conclusion, "Pocket Square" by Rajiv Mathur is a commendable effort to showcase the human side of the cybersecurity world through an innovative and relatable lens. It’s a recommended read for anyone curious about the intersections of technology, personal branding, and the untold stories of those who keep our digital lives secure.
