“Nimue and the Terror King” is coming out on Oct. 6! Click here to preorder.

Reviewers on Goodreads have said that it has a “dark Wizard of Oz vibe.”

Here’s how the story goes:

Sixteen-year-old Brett escapes into fantasy novels to cope with his parents’ divorce — until a one-armed girl appears from the pages of a book he’s reading with no memory of who she is or how she got there.

Before Brett can figure out who she is, they are attacked by a powerful sorceress and the sworn enemy of the mysterious girl, Nimue.

Brett inadvertently transports them back to Nimue’s world, where she remembers who she is: a tribal leader of a persecuted people. She vows to kill the Terror King, the tyrannical ruler responsible for their suffering, by any means necessary.

The only way for Brett to get home is to find the book, which has been taken by the sorceress deep within the Terror King’s capital city. But he can’t get there without Nimue.

Brett must decide whether finding his way home is worth helping Nimue sacrifice millions of innocent lives.
