I’ve just, that is, on the first day of ICEHL-19 in Essen, been told about yet another review of the book, by Nuria Calvo Cortés from the Universdad Complutense de Madrid. The review appeared in the journal Atlantis, and (to my delight) is freely available online.
A second review appeared on 15 July 2015 in the journal Women’s Writing, by Jane Hodson from the University of Sheffield.
And here is a third one, by Katie Halsey from the University of Stirling. It appeared in the Autumn issue of The BARS Review (no. 46).
And if you wish to read more about the language of the letters, see the proceedings of the most recent Anglistentag (Hanover, 2014).
