CHRIS GRINE is the creator of the Eisner Award-nominated Chickenhare and Time Shifters . He's been making up stories since he was a kid, and not just to get out of trouble with his parents. Nowadays, Chris spends most of his time writing and illustrating books, drinking lots of coffee, and sleeping as little as possible. He spends his free time with his wife, playing with his kids, watching movies, and collecting action figures (but only the bad guys). K.A. Applegate is the married writing team Katherine Applegate and Michael Grant. Their Animorphs series has sold millions of copies worldwide and alerted the world to the presence of the Yeerks.

Katherine is also the author of the Endling series and the Newbery Medal-winning The One and Only Ivan . Michael is also the author of the Front Lines and Gone series.
