As a writer, this
is a must-have for your shelf, whether your write nonfiction,
novels or anything in between. Beyond the first 14 pages
that cover grammar and punctuation are invaluable sections
on Principles of Composition, Commonly Misused Words,
and perhaps the most valuable: An Approach to Style,
which gives excellent advice along the lines of Do not
overwrite, Avoid qualifiers, Don't over-explain, Avoid
adverbs, Avoid dialect, Don't inject opinion, and tons
of others.
