Ruby is curious about her world and has big ideas about how it works. A delightful picture book celebration of science and creativity, and a welcome companion to Sara O'Leary's beloved This Is Sadie.

Ruby is a little girl with a sense of curiosity and enthusiasm that's too big to contain! Ruby is always busy -- she loves to make things, watch things grow and figure out how things work, with her dog Teddy by her side. And Ruby has lots of ideas about what she wants to be: maybe an animal conservationist? Or an archaeologist? She's great at excavating (i.e. digging holes). Or maybe an inventor? She's already invented a book with smells instead of words (so dogs can read it) and a time machine (the dinosaurs did have feathers after all, and the future is looking wild). This is Ruby, and this is her world.
