As a writer with expensive tastes myself, I didn't have a very difficult time relating to the struggles of India Palmer. The first half does an excellent job at showing how even a successful couple of fairly artists (if I remember correctly, India says she and her husband bring in around $150,000 a year) struggle with New York City living, and sets up just the right circumstances for her to take the proposed Pygmalion deal. While India can come off as a little self-pitying in this part of the book (poor little miss can't keep up with Joneses), her reasoning for sacrificing what she does makes perfect sense - if she had been the true starving artist type, I don't know if the plot would have worked as well. It's a good commentary on the absurd expensiveness of raising a family in Manhattan, and creates a nice "My Fair Bonfire of the Vanities" story.
Though the second half of the book was entertaining, it was more vignettes about India's new life than a storyline, and I think this is what my biggest criticism is - there was very little conclusiveness (perhaps mirroring real life, but dramatic liberties exist for a reason). Despite India's initial reluctance to take on the deal, it turns out she's a much better bonds trader than a writer, at least from a financial perspective, and once that ball starts rolling, she very rarely pauses to think, "...but am I betraying my artistic value?" There wasn't a lot of follow through on the initial conflict, no doubt, and definitely no turning back. It remains a good read, and the fish-out-of-water experience for India as she really gets to take control of her life was fun, but it's a little disheartening to see someone so insistent on being a writer throw it all away. It also could have benefited with India having more conflict - her family was all too supportive, her friends too indulging, her money issues insignificant for most people.
Still, most definitely a recommended and worthwhile read!
