He grew up in rural Cochranton, Western Pennsylvania, where he attended school in a one room schoolhouse. He graduated with a B.A. in English from Grove City College in Pennsylvania. While a college student, Blackwood published his first short story, Cliffs of Gold, in Twelve/ Fifteen magazine.
He has sold dozens of stories to children's magazines, and has published thirty-five novels and nonfiction books for adults, young adults and middle readers.
This was one of my absolute favorite books in 3rd and 4th grade. Partly this is because my parents had a really outdated set of science books from the 40s in our family library which blurred the lines between science fiction and fantasy. I loved the idea of space exploration and that there could be other worlds within travel distance.
