If I were to analyze McCarron based on these stories, I’d suggest that she has some issues that need working out. Tetris is a story about an icky, abusive relationship centered on violence and mutilation; The Magician’s House is about an icky, abusive relationship borne of an older magician’s ability to manipulate his student. Ick and abuse all around!
But I don’t actually think she has issues, mostly because (a) I’ve never met her and know nothing about her, and (b) writers are not their stories. Item (b) is the important one, here. I hate to think what someone would think who was diagnosing me based on the stuff I’ve written.
