Francisco X. Stork.
Titles I've written about:
Marcelo in the Real World (2009):
Marcelo's voice is wonderful and believable and different. He has some childlike qualities, and those qualities, along with his "disorder", make some people underestimate him and try to manipulate him. But, as he says, he perceives reality just fine. His time in the real world changes him, and it changes some of the people around him. It's a lovely, lovely book.
Irises (2012):
While the logical side of me thinks that the language works the way Stork meant it to, the rest of me found the book significantly less satisfying—and certainly less enjoyable, because I felt like I was always fighting the prose, rather than being drawn along by it—than Marcelo.
