It seems lately that I've been doing an endless round of blogs, emails, and posts. When I haven't been doing that, I've been doing research. As is my habit, I've gone way overboard on the amount of reference material and writing books I've been sinking into. (Including being a super backer on Kickstarter now, having supported my 80th Kickstarter. Almost all of them on something world building related)
But that brings to one of the many writing books I've zipped through recently. Write Right! A desktop Digest of Punctuation, Grammar and Style by Jan Venolia (Linked to the amazon print version above via an affiliate link to Amazon that hasn't paid squat in years). This is a great little book that condenses a lot of things into one handy book. I intend on using it as one of my references and inspirations for weekly blog that we are planning on starting up in the new year.
But if you are a writer and you are looking to improve your grammar, this is a good tool for that.
