Book excerpt: Tifanny Gia's all set to explore and learn (and maybe be a hero) in Civ-Alpha as part of her Aunt Gina's advanced archaeology class. But Gina's substitute, Prof. Trixie Rabinowitz (ex-ruler of Graceneria and big sister of mercenary Dark Bird), figures a Saurian playground's a nice, safe, dull assignment for the "class baby!" Will Tif's dad be able to counsel her past this trial, or will the "baby" throw a tantrum that'll ruin her teacher's life forever?
