Conversation analysis has opened up a new frontier for both Conversation Analysis (CA) and second-language acquisition (SLA). It is a gutsy and timely book. As a first endeavor of its kind, it ventures to apply an increasingly popular discourse analytic methodology to a field whose research has traditionally been governed by experimental paradigms. It also strikes an impressive balance between theoretical considerations and empirical analyses. The book begins with purely theoretical discussions on the larger issues that govern the two fields, then moves on to incorporate empirical data in illustrating the possibility of connecting them. The theory-to-practice continuum is completed by applying CA to two SLA-related collections of data. In a remarkable way, the author manages to become fully engaged in micro-analytic procedures without for a moment losing sight of the larger pictures that motivated these procedures.
