When one of the Mighty Mighty Monsters' pets goes missing, they all must lend a hand, or a paw, or a claw. . .

As a lifelong comics fan, Sean O'Reilly dreamed of becoming a comic book creator. In 2004, he realized that dream by creating Arcana Studio. In once short year, O'Reilly took his studio from a one-person operation in his basement to an award-winning comic book publisher with more than 150 graphic novels produced for Harper Collins, Simon & Schuster, Random House, Scholastic, and others. Within a year, the company won many awards including the Shuster Award for Outstanding Publisher and the Moonbeam Award for top children's graphic novel. O'Reilly also won the Top 40 Under 40 award from the city of Vancouver and authored The Clockwork Girl for Top Graphic Novel at Book Expo America in 2009. Currently, O'Reilly is one of the most prolific independent comic book writers in Canada. While showing no signs of slowing down in comics, he now writes screenplays and adapts his creations for the big screen.
