About the Author

S.J. Kincaid is the New York Times bestselling author of The Diabolic trilogy. She originally wanted to be an astronaut, but a dearth of mathematical skills made her turn her interest to science fiction instead. Her debut novel, Insignia, was shortlisted for the Waterstones Children’s Book Prize. Its sequels, Vortex and Catalyst, have received starred reviews from Kirkus Reviews and Booklist. She’s chronically restless and has lived in California, Alabama, New Hampshire, Oregon, Illinois, and Scotland with no signs of staying in one place anytime soon. Find out more at SJKincaid.com.
