Stories from Switchblade No. 2, edited by Scotch Rutherford:

The protagonist in “My Brother’s Keeper” by Rob T. White, wakes to a living nightmare, bound and gagged by a couple of masked strangers intent on torture. As he drifts in and out of consciousness between sessions, he slowly pieces together a possible reason for this horror. Thankfully, there’s more to this story than its cringingly vivid action.
