The Negative struggles a lot as Silk doesn't come across as particularly likable. There's a fine line between a hard luck hero/heroine and one that's whiny and navel gazing. Unfortunatley, Silk falls into that patterns. While she understandably and realistically has issues after what's happened to her, Thompson doesn't do a good job helping us to see as strong or admire her. See Sam Humphries characterization of Jessica Cruz in Green Lanterns to see how this is done right.
In addition, there are some plot twists that are weird and out of nowhere for the type of book this has been. Overall, can't say I'd recommend this one.
