The book is written in English and teaches a more advanced level of Finnish. This would be the next step after Leila White's "From start to Finnish". Unlike that book, "A Grammar Book of Finnish" has no pictures. No exercises in this book, either. Just Finnish grammar in black and white ink, from inside cover to inside cover. She'll explain a Finnish grammar law and give examples in the form of sentences. Every example has a Finnish and English translation. Very pragmatic book.
