Grief is something that humans must experience in little ways every day. Unfortunately, some of us are ripped at the seams by the losses we suffer, but Katherine Everett has seemingly stitched herself together again with the utmost care and creative craftsmanship. I have never seen such keen excavation on stage, held in perfect time, to the beat of a sister’s broken heart. I believe we only understand the big things by truly knowing the little things, and in her play, “Texas Hellfire,” Katharine guides us to the ineffable. I hope that I will be able to wade into waters of this stunning performance again. Once would never be enough.
