The third in Cassandra Clare’s “Mortal Instruments” series, “City of Glass," follows both of its predecessors in making the Teens Top 10 list. Readers can’t help but draw parallels between this science fiction series and fellow teen favorite “The Hunger Games.” Both feature a boy-girl team of brave teenagers (the girl gets the protagonist role), a little romance, and a lot of fighting for survival in an alternate world. Whereas in “The Hunger Games” the characters combat fellow humans and the government, in “Mortal Instruments” enemies are mythical: demons, monsters, and other magical creatures.
