I have hardcover copies of Fallout Equestria from a fan printing project. And even the one that managed to get it into a single volume with thin pages and small print is as thick as my wrist. And Project Horizons is nearly three times longer than that. ^_^;;Personally I'd suggest going to FimFiction.net and downloading the PDF copy of it. Then you can put it on your phone/tablet and read anywhere. As well as search the whole thing for any word or phrase if need be.The download button is just under the chapters list.
