This is definitely not the extent of the numerous uses you can put も to work!

I bought this Japanese grammar book when I first started to learn Japanese, and it has helped me immensely to learn all the uses of the elusive "Particles".  Definitely a bargain price for such a wealth of information.

I recommend this book to beginners and intermediate users alike.
