With this edited volume, Byrnes has added one more publication to the growing body of literature (of her authorship and that of others) on advanced language learning (ALL). In this collection, the notion of advancedness in language learning and instruction is explored through a very special lens: the illuminating potential of Halliday's systemic functional linguistics (SFL) and Vygotskyan sociocultural theory (SCT)...This is an excellent volume. The chapters are all well written and rich in stimulating ideas. The book balances adequately the theoretical with the practical, offering support for a new approach to L2 classrooms that truly places meaning at the center of instruction and makes ALL both a possible and desirable goal...serves wonderfully as a point of departure for exploration of aspects of meaning, context, and use in advanced language teaching and learning from an integrated SFL and SCT perspective.
