Inkling

Inkling is one of Mark's favourites of 2018.
 
When Ethan's class is given the task of creating a graphic novel and magical ink jumps out of his father's sketchbook, a strange series of events is set into motion.

To his younger sister, Inkling is Lucy, her beloved dog; to his father, Inkling is a second chance at a dwindling career and a chance to solve his family's money worries. Friends and enemies alike try to use Inkling to ace tests and create bestselling comic books, but to Ethan, Inkling is his friend - and he must do everything in his power save him.
