To Sir with Love (Used)

E.R. Braithwaite's autobiographical novel follows Mark Thackeray, an immigrant from British Guiana who takes a teaching post at a tough London secondary school despite having no teaching experience. After his initial strict approach fails, he begins treating his unruly, distrustful students as adults, gradually winning their respect and transforming the classroom — culminating in the students presenting him with an engraved tankard reading "To Sir, with Love."
