Boom! Studios is in the midst of a four issue limited series expanding on the 2014 Cartoon Network mini-series (whose virtues I've extolled before), Over the Garden Wall. The series presents additional adventures of Wirt and Gregory in their wandering through the fairy-tale like Unknown as they attempt to find a way back home. It manages to well-capture the series' feel--not surprising since the writer is the show's creator.
Issue #1 is set between episodes 3 and 4 of the mini-series. Wirt, Gregory, and the bluejay Beatrice are trying to get to the house of Adelaide of the Pasture. They wind up attending a tea party and performing odd chores (which Wirt can never get right). It all ends in tears--a house's tears, in fact--and the trio moves on.
Issue #2 takes place between Episodes 4 and 5 and features the backstory of Fred the horse who joined our protagonists when they left the tavern at the end of Episode 4. It features the foibles of over-honesty, and a strange encounter with a perhaps-ghostly Highwayman (the same one who sang the song in Episode 4) in a covered bridge at night.
Two more issues are to come.
