"De Havermelkelite" offers a captivating portrayal of the trendy lifestyle and social changes that have significantly impacted Amsterdam. Written from the perspective of Jonas Kooyman, who initially observed these trends and gradually became part of this new lifestyle, the book provides an insightful critique of modern consumerism and the relentless pursuit of pleasure and diversion.

As a reader, I found that the book effectively highlights the emptiness of consumerism and the societal shift towards superficiality. Kooyman illustrates how Amsterdam has been fundamentally transformed by these changes, reflecting a broader commentary on contemporary society's values and priorities.
