ElizabethN, I hope she likes it. For most 9-year-olds I'd start with Chapter 1 to build comfort. For some advanced and/or impatient kids Chapter 2 can will be a better place to start to let them know there will be things that are more novel.
Thanks! I'll report back how it goes. My experience is that sometimes she dives in full-bore, and sometimes she refuses to look at something for a while and then "sneaks" it when I'm not around.
She just finished 4th grade math (she's in a gifted program that works one year ahead), so I think she's probably right in the sweet spot for it.
