Mutation, cancer and malformation Book

I am a Master's student of French with an undergraduate degree in French language and linguistics. I am also a French language proctor for proficiency exams.

This is the best advanced grammar book I have ever used. The explanations are in English to facilitate understanding with an English-speaking audience. The details in the book are completely nuanced and contextualized, giving you a very thorough understanding of each aspect of the language. Even reading the beginning section on "présent" or "passé composé" taught me a multitude of nuances that I was not yet familiar with.

Bref - buy the book. It's more than worth it if you're a serious student.
