The greatest benefit of Pepin’s work is that it provides an accessible introduction for those who are unfamiliar with the history. It is a relatively slim and entertaining book that is easy to read, and Pepin does an excellent job of explicating the political circumstances surrounding complicated issues, such as the papal bull that María and Sancho sought to secure their dynasty. Furthermore, she makes connections between María’s rule and that of her female relatives, which serve to contextualize her exercise of queenship. . . . Pepin’s work and the attention that it brings to this obscure, yet worthy subject are most welcome.
