“This is an excellent introduction to the ‘Epoch of Reionization’. … It is very timely, as it is a relatively new frontier in several senses … . this is an excellent collection of articles that give a balanced and comprehensive review of the state of the subject, and it is thoroughly recommended for students embarking on the topic, for the wider community of cosmologists, and for experts in the field, who will probably also learn something new as well.” (Alan Heavens, The Observatory, Vol. 137 (1256), February, 2017)
