Michael Grant has spent much of his life on the move. Raised in a military family, he attended ten schools in five states, as well as three schools in France. Even as an adult he kept moving, and in fact he became a writer in part because it was one of the few jobs that wouldn’t tie him down.

Michael is the author of the bestselling Gone series, the BZRK trilogy and the brand new Front Lines trilogy, the first book of which released in March 2016. With his wife Katherine Applegate, he is also the co-author of Eve and Adam and the Animorphs series, and has written or co-authored over 150 books, which by his own admission is just absurd!

Michael lives in the San Francisco Bay Area with Katherine and their two children, 18 and 15 (because numbers are so much easier to remember than names).

Katherine Applegate is the author of The One and Only Ivan, winner of the 2013 Newbery Medal. Her novel Crenshaw spent over twenty weeks on the New York Times children's bestseller list, and her first middle grade standalone novel, the award-winning Home of the Brave, continues to be included on state reading lists, summer reading lists, and class reading lists.

She lives with her husband, the author Michael Grant, who she co-wrote the Animorphs series with, and their two children in Northern California.
