" Rumo was a fun read, but it lacked the magic that made City of Dreaming Books so excellent and special. The ideas and language and characters are far less compelling - they're just "imaginative" and "quirky" without being truly creative, which makes it feel its childishness felt more strongly. It also reveals the weaknesses of the plot, which, as in all Moers books, is pretty tropy and predictable. The world feels strangely small in this book, because Moers essentially writes every piece of lore he mentions into the main plot line - the things that are presented as old, big, world-spanning become Rumo-scaled and completely lose any mystery they may have had. Still a fun read, escapist stuff for a stressful day, etc. "
