Equal Rites by Terry Pratchett

The Disc's first female wizard was created nine years ago, accidentally, and now Granny Weatherwax is fighting to get Esk the instruction necessary to control her magic. With untrained magic, anything can (and does) happen.

This one's prime Pratchett, as he knocks tradition sideways with a new world order built around a strong, determined girl wizard and her tenacious witch mentor. Esk also befriends Simon, another wizard-to-be who's also got special talents.

Dear Ijeawele, or A Feminist Manifesto in Fifteen Suggestions by Chimamanda Ngozi Adichie

Addressed as a letter to a friend seeking advice, Adichie gives a brief, powerful primer on feminism in a changing world.

While it's addressed to a new mother on raising her daughter, the lessons are equally important for anyone. We all impact the next generation, and the first steps to change must be our own.

It's an amazing, succinct piece with a lot to ponder. It's probably worth repeated reading and is truly the kind of book you should buy to revisit annually.
