Langenscheidt German Grammar in a Nutshell: Deutsch als Fremdsprache. Englisch-Deutsch (Langenscheidt Grammar in a nutshell)

Not great if you are just starting out, it doesn't explain the English concepts so if you are not 100% on your grammatical terms it's a bit difficult to use. I found another one that went from no knowledge and built up

Hat viele einfache geschriebt infomationen und Übungen. Es ist auch kompakt und hilfreich.

Really good book for learning. All grammatical rules from A1-B2 are in one book. A lot of words, good exercises. Many formulas, tables, notes and examples. Really useful for carrying everyday to study\courses.
