Follow the adventures of Zoey and her cat, Sassafras, with this collection of books one to six in the series. Each story features a new magical animal with a problem that must be solved using science. There isn’t a set formula for each book; Zoey sometimes needs to run experiments, while other times she needs to investigate a mystery, and yet other times she needs to do research. Zoey models how to keep a science journal through her handwritten entries in each story.

This journey will lead to sinister umlauts, a trash-talking goat, and the Dread Necromancer Steve....

When Molly shows up on Castle Hangnail's doorstep to fill the vacancy for a wicked witch, the castle's minions are understandably dubious. After all, she is 12 years old, barely five feet tall, and quite polite. (The minions are used to tall, demanding evil sorceresses with razor-sharp cheekbones.)

Oh, it's not the very cute kitten that appears out of nowhere and demands to go home with her.
