Tarek El Diwany's seminal book "The Problem with Interest" exposes how interest-based finance fuels inequality, instability, and moral decay—arguing for ethical, debt-free alternatives rooted in justice and real economic value. Tarek is my teacher and friend. I first met him at a conference in Leicester, back in 2007. Since then, I've had the second and third edition. The new fourth edition comes in hardback format:

T P W I - Helping people understand banking and finance

The Problem With Interest - T P W I

The Problem With Interest by Tarek El Diwany in hardback. Fourth edition with a slightly larger font for easier reading.
