Books with title Jennifer, Hecate, Macbeth, William Mckinley, and Me, Elizabeth

Elizabeth is an only child, new in town, and the shortest kid in her class. She's also pretty lonely, until she meets Jennifer. Jennifer is...well, different. She's read Macbeth. She never wears jeans or shorts. She never says "Please" or "thank you." And she says she is a witch. It's not always easy being friends with a witch, but it's never boring. As first an apprentice and then a journeyman witch, Elizabeth learns to eat raw eggs and how to cast small spells. And she and Jennifer collaborate on cooking up an ointment that will enable them to fly. That's when a marvelous toad, Hilary Ezra, enters their lives. And that's when trouble starts to brew.

Elizabeth is an only child, new to town, and that can be very lonely. So when she meets Jennifer, a girl from her school - who claims to be a witch no less - she is eager to become her apprentice. Over the course of the next several months, the girls meet on Saturdays for their weekly rituals and read volumes on witchcraft in hopes of developing a flying ointment. But they do not find the best magic in Jennifer's black cauldron.
