Tamra B. Orr

Tamra Orr is a full-time writer and author living in the gorgeous Pacific Northwest. She loves her job because she learns more about the world every single day and then turns that information into pop quizzes for her patient and tolerant children (ages 16, 13, and 10). She has written more than 80 nonfiction books for people of all ages, so she never runs out of material and is sure she’d be a champion on Jeopardy!
