Cambridge University Press remains at the forefront of publishing network science books.' Stanley Wasserman, Indiana University, Bloomington, and National Research University Higher School of Economics, Moscow 'This is a comprehensive guide to a fascinating mathematical and computational perspective on real-world social phenomena ... Overall, the book provides a thorough introduction to multilayer social networks, followed by an extensive literature review. The intensive interest and the enthusiasm of the authors for this area are contagious and stimulate the readers to further explore multilayer networks as tools for their own research domains. Hence, the book is recommended to researchers, practitioners, and teachers who are eager to 'escape from Flatland' and investigate new dimensions.'
