Teaching Idea #1 ~ Comparing Two Books with Underground Settings

Underground settings have been popular for years. One of the first books with this setting was Journey to the Center of the Earth (1864). Just a year later Alice’s Adventures in Wonderland (1865) was published.
The City of Ember is a great book to compare to Gregor the Underlander. In one scene of the book, Gregor tries to escape from the Underland by riding a boat down the river. Although Gregor’s journey ends in a vicious fight with rats, the actual boat ride resembles Doon and Lina’s ride out of Ember.
