I am a bit cognitively challenged by print media that combine text and image (comic books, for example). This children's book does just that: faux-handlettered font with arrows pointing back and forth, sentences meandering up the side, interspersed doodle illustrations, maps and diagrams, boxed-in words -- and all of this madcap page design echoed in the madcap and narratively meandering story of adventure, intrigue and evil schemings.
The format is 'journal' (think Diary of a Wimpy Kid). The tone is irreverent and breezy. I think I might have liked this a lot as a child, and I would have immediately copied it for my own purposes. The only thing: I am not 100% the addressed reader. The first-person journalling main character is a boy, his bestie is a boy, his school dorm mates are boys, his nemesis is a boy, the evil overlord and his henchmen are boys, the captain of a ship is a boy-- do you see a pattern here? There is one girl whose name the MC keeps getting wrong and who is feisty with a knife and awesome in a fight (so she is in fact an Honorable Boy). I was surrounded by stories like this as a child: adventures with boys and One Honorable Boy-Girl whom latter I of course wanted to be. Boys, let me be one of you, please! Today's me says: Authors, let there be more diverse people!
There is one other main female character: she is the dinner lady. @-@
Full disclosure: I am not in my entirely right mind, having purchased this in the wake of Our Flag Means Death, and my brain may have been addled during Reading and/or Reviewing. Long may it roam! (my brain)
PS It is written and illustrated by Rhys Darby. It has cryptids in.
