In this captivating quest that spans the globe, a young girl who wants to know everything challenges her assumptions about family, loyalty, and friendship as she fights to save her father's legacy--and to begin creating her own.

Hallelujah Wonder wants to become one of the first female scientists of the nineteenth century. She knows every specimen and rare artifact that her explorer father hid deep in a cave before he died, and she feels a great responsibility to protect the objects (particularly a mesmerizing and dangerous one called Medicine Head) from a wicked Navy captain who would use it for evil. Now she and her friend Eustace, a runaway slave, must set out on a sweeping adventure by land and by sea to the only place where no one will ever find the cursed relic... the cold of Antarctica.
