This is an outstanding report of qualitative longitudinal case studies that illuminate L2/L3 WTC development in immigrant women. Momentary fluctuations in WTC are zoomed in on and then out to showcase stories embedded in macro-social contexts. The expansion of the WTC Model to multilingual 3D graphics is a stimulating addition to WTC literature.
