Rob Renzetti is a veteran of TV animation whose work on Cartoon Network's Foster's Home for Imaginary Friends earned him an Emmy. He created the Nickelodeon show My Life as a Teenage Robot, acted as the supervising producer for Disney's Gravity Falls, and served as executive producer on the first two seasons of Disney's Big City Greens, among other projects. Recently, he has published four books for Disney Publishing, including the #1 New York Times bestseller Gravity Falls- Journal 3 and Onward- Quests of Yore.
""The heart of the story is Renzetti’s immersive world, populated by otherworldly characters like the quippy Schrödinger’s Cat and Zenith’s likable, trusty, and quirky gargoyle sidekick, Kreeble. What stands out most among the fantastical elements is the fierce love between Zenith and Apogee and their deep appreciation for the many creatures in GrahBhag… A rewarding ending to an imaginative, wholly original series.""—Kirkus Reviews
