Practice Makes Perfect: French Pronouns and Prepositions (Practice Makes Perfect Series)

Most grammar books cover a lot very quickly with just a couple of examples. This book covers a smaller area but very thoroughly. The workbook format encourages you to write on the book but at it's minimal cost, that's fine. Fairly heavy going, as you'd expect but by the time you've worked your way through this, you will have a good A level understanding of pronouns/prepositions. Recommended.
