Steven King's On Writing
Zinsser's On Writing Well
Also, some of the posts are recommending one book instead of another book, but being counted as a recommendation for the book that's not being recommended.
For example, someone recommended the Algorithm Design Manual as an alternative to Introduction to Algorithms, but its counted for the latter.

Gotta keep updating those priors :)
Wish you the best OP.
