Thank You, Elana Johnson, for writing a character with a "Z" name, and quite a good character!
Zenn is Vi's perfect match, and the Thinkers have chosen him to be Vi's mate. He comes across as a poster boy for The Goodies, or conformity in their brain-washed world, but for me he has an understated strength about him. He wants to be with Vi and love her, but she's always in trouble. He believes in her. He's quiet and content. He reminds me a lot of Peeta Mellark whose shares that charismatic quality.
