The book "Students' presupposition, prejudice, and discrimination in an English class", as the name says, analyses assumptions of students when they discussed about professions in the context of an English language clasroom. Inserted on the field of Critical Applied Linguistics (CAL), Egido's research is composed by an extended literature review, where he carefully approached a detailed panorama of CAL nowadays, giving us a better understanding on where his investigation sits and which gaps it fills. Besides that, he discussed the themes mentioned in the title, which are derived from a Paradigmatic and Syntagmatic analysis – both a method and a methodology for qualitative research – that shows total connection between the theory presented and the data analyzed making the book even more interesting. Other aspects of this investigation are worth to be cited, for instance, the ethical procedures used with the participants and the deep analysis brought by author, demonstrating the importance of researching gender, ethnic and prejudice in the educational sphere. I believe this work will be a great support for professors, students and researchers concerned with issues related to teacher training processes, as we can clearly see how the teacher dealt with students' responses. Also, it is a valuable source for the ones interested in studies about cognition, especially those inserted in CAL.
