Stories about best friends set against the backdrop of competitive, high-stakes, art-based industries: this is what I live for! Think THE BALLERINAS by Rachel Kapelke-Dale and SMILE AND LOOK PRETTY by Amanda Pellegrino.
I love novels that deal with female relationships. Think: best friends; mother-and-daughter(s); sisters (incl twins!); sisters-in-law; mother-in-law and daughter-in-law; and girlfriends. Bonus points above apply.
