Indie writing shines in Wool.
First off, don't bother buying Wool #1. Just buy Wool Omnibus and save a couple of bucks. You won't just read the first book, you'll be reading all of them.
Howey's writing is well polished and puts to sleep any notions that indie writers are all hacks. It's as well-edited as novels of similar genre found at brick and mortars stores.
All that said, I found the first three books the most intriguing. (I gave Wool #2 4-stars but, in retrospect, that story has stuck with me.) He bravely goes where Faulkner implored us to go and killed his darlings in heart-wrenching fashion as the story of where and why unfolds. Like many good writers, he put me in the ground and I felt the cold ring of the spiral steps and the dampness of the down deep and buzz of the monitors at the top.
I think that's why my interest fell off in #4 and #5. He stopped killing. While it quite satisfyingly resolves the loose ends of silos, I found myself speeding through the text to see where it went rather than savoring the slow creation of characters in #1 through #3.
Nonetheless, Wool is here to stay. I'm happy to say I read it before it became a blockbuster and Hugh Howey makes millions.
Well done, sir.
