'This book takes us out of our comfort zone in critically examining the evidence for supposed convergence between Spanish and English in the Southwestern United States. It sets new standards in language contact research and the team of Rena Torres Cacoullos and Catherine Travis has produced an impeccable study, using state of the art methodology and analytical tools.'
