The City of Ember (The First Book of Ember)

Twelve-year-old Doon Harrow and Lina Mayfleet seem to be the only people who are worried. They have just been assigned their life jobs--Lina as a messenger, which leads her to knowledge of some unsettling secrets, and Doon as a Pipeworker, repairing the plumbing in the tunnels under the city where a river roars through the darkness. But when Lina finds a very old paper with enigmatic "Instructions for Egress," they use the advantages of their jobs to begin to puzzle out the frightening and dangerous way to the city of light of which Lina has dreamed. As they set out on their mission, the haunting setting and breathless action of this stunning first novel will have teens clamoring for a sequel. (Ages 10 to 14) --Patty Campbell
