"The Call of the Wild" by Jack London. An audiobook is also acceptable for use in this class, although I encourage a physical book along with the audiobook, if possible.

Parents should be aware of the following sensitive content in "The Call of the Wild" by Jack London:

Violence: The novel contains scenes of animal violence and brutality, including dog fights and harsh treatment of dogs by humans. Buck, the protagonist, experiences and witnesses considerable physical hardship and conflict.
   
Death: There are several instances where animals die or suffer due to harsh conditions, mistreatment, or natural predation, which can be distressing to sensitive readers.

Survival: The book vividly describes the struggle for survival in the wild, which includes depictions of hunger, cold, and the brutal realities of life in the Klondike during the Gold Rush.

Treatment of Animals: Characters in the book often treat animals cruelly, which reflects the historical context but may be upsetting for young readers or those sensitive to animal welfare issues.

Nature: The novel portrays nature as indifferent and often harsh, which can be a stark contrast to more idealized representations of nature.

Discussing these elements with your children before they read the book can help prepare them and provide a framework for understanding the historical context and themes of survival and transformation before they attend class.
