Justin Grimmett was born in a small town in Idaho during the mid-Seventies. Very early on in life, he was very creative. He was never far from a box of crayons as a youngster. He constructed elaborate dioramas or giant birthday cards for his classmates. For most of his life, he assumed he would become an artist. As a teenager, he developed a love for comic books. He also became interested in the writings of Stephen King and Joseph Campbell. Native Americans and other indigenous folklore inspired him, and he would take any opportunity to catch a play or read a myth.
After graduating from college, he started experimenting with writing science fiction. To date, he has written six books.
