Since I didn't get around to writing a post yesterday, here is a second post for today!
Recently, Rick Riordan has been posting pictures of "mystery locations" for The House of Hades on his Instagram account, which are basically real places that the characters are going to visit in the book. Let's find out what they are!
Mystery Location #1
Google Search says... nothing. -_-
Google search says... The Fountain of Neptune in Bologna, Italy!
Mystery Location #2
Google search says... St. Mark's Clock Tower in Venice, Italy!
Mystery Location #3
Google Search says... the Ruins of Salona in Solin, Croatia! We will also see demigods encounter a god here.
Mystery Location #4
Google search says... Valletta, Malta! The Argo II will dock here.
It definitely sounds like we're going to have a lot of Europe in store this book!
