"Some books are dangerous to read while you're writing, because you'll start to sound like them."
I have definitely had this happen to me before, where the things I write down can echo the latest things I read if I'm not careful. However, I also believe in the power of a mentor text.
Right now I am editing the manuscript of my first novel, and at the same time have been reading The Shipping News by Annie Proulx. She has this uncommon mastery over creating her sentences with absolutely no extra words. There are several sentences in her writing with only one or two words to them, usually barely more than a verb. Her writing has revealed to me exactly how wordy I can be, which is perfect while I'm in editing mode. Many sentences in my paper copy are squiggled-through as I'm realizing how redundant they are.
Being aware of the voice in what you're reading is clearly important to note while you are writing. Some habits if you were to pick them up may not be compatible with the way you write, while other writing may be useful to keep on your nightstand if one writer has a strength you were/are looking to incorporate.
Which writers do you use as mentor-texts? Which take you over, that you try to avoid?
