Wonder at the Edge of the World (First edition)

Hallelujah Wonder wants to become one of the first female scientists of the nineteenth century.

Her father was a scientist and explorer, but his life was cruelly cut short by an evil Navy captain who coveted his cache of artifacts.

Hallelujah feels a great responsibility to protect the objects--particularly a mesmerizing (and dangerous) one called the Medicine Head--before the captain can succeed.

Now she and her best friend, a slave boy about to be sold, must set out on a sweeping adventure by land and by sea to the only place where no one will ever be able to find the cursed talisman: the forbidding land of Antarctica.
