Author Biography

Chris Schwarz was born in Moline amidst amber waves of grain and green tractors. He grew up reading J.R.R. Tolkien and Robert Heinlein, ultimately becoming an engineer rather than a wizard, but not by choice. The son of an immigrant, he was the first in his family to attend college. Along the way he picked up a Ph.D. in engineering and learned to Salsa dance. By day he writes about research on advanced vehicles done with a big ole’ driving simulator, and by night he writes his own stories. He is the author of a young adult series featuring four high school friends solving mysteries tinged with science and technology. Its first installment, The Cache, is coming soon. Fueled by chai lattes and dark chocolate, Chris lives in Iowa City with his wife, son and dogs, and waits patiently for self-driving cars to figure out snow.
