'This book is a rigorous, fascinating, and provocative analysis of the dramatic challenge faced when pursuing peace and, at the same time, accountability. The authors' robust, honest, and sometimes controversial reflections make this a must-read for those who want to understand the theory and practice of negotiating transitional justice and ending violent conflict. The lessons it offers can literally save lives.' Catalina Botero Marino, Dean of Law Faculty, Universidad de los Andes
