A great critical introduction. And I say "critical" because Peter Marshall's book is about historiography just as much as it is about history. Indeed, he probably cites upwards of a hundred critical texts over the courses of these pages—highlighting academic controversies and outlining recent developments. Of course, this means that Reformation English: 1480-1642 will be of little interest to the layperson. But nonetheless, it's an impressive work of scholarship and an effective overview of a convoluted yet fascinating period of English history.
A brief caveat: Marshall's syntax is occasionally tangled and he has a tendency to introduce a historian or historical figure by last-name only, which suggests that this book was rather hastily put together. At the very least, it might have benefited from the eye of a more perspicuous editor.
