Picture book, where the protagonist travels around the world looking for monsters

[Vexing1000]

Read between 2008 to 2016

Large picture/adventure type book for young adults. Written in a first person exploration log type format; the protagonist travels around the world by him/herself looking for (some quite lovecraftian) monsters and it does not go well for him/her.

Lots of artwork on every page, may have had a few puzzles in it as well.

Vexing1000, is the main character hunting/searching for monsters in general or looking for a specific one? Why?

Is this a graphic novel? Can you describe the illustrations - simple/detailed, realistic/cartoony/cute, painted watercolors/bold graphics, bright/dark/muted colors/black & white?

Do they remind you of another illustrator or author?
