Books
Hi EGKB,
There are two book series in common use. The 'Trevor Thom' series and the 'Jeremy Pratt' series.
I believe Trevor Thom himself died some years ago, so his books have been updated by other authors. However I have found the Thom books to be stogily written and so make for heavy reading, but they do cover the ground.
Personally, I prefer the Jeremy Pratt books, which I find much easier to read.
In particular, I suggest you do not buy a whole series. Buy your books one at a time, because you may find the Pratt book better for one subject and the Thom book better for another.
Good luck!
BP.
