Nora Alpers has just become a ten-year-old aunt. To prepare for the new arrival, Nora has been writing down baby-related facts in her special notebook, just like she does with her favorite subject: ants. She likes the idea that someone who studies the A-N-T is also an A-U-N-T, even though she doesn’t know anything about taking care of babies. A new family member isn’t the only thing stressing Nora out. At school, Nora has to write journals in the voice of a pioneer on the Oregon Trail and prepare for the annual science fair. Science is normally Nora’s best subject—until Nora ends up being paired with science-hating, cat-obsessed Emma! How will Nora ever learn to be a good aunt if she’s trying to survive the Oregon Trail and arguing against Emma’s unscientific science-fair ideas?
