Overview:
This book follows two friends named Iris and Sam who grow up in this boring town called Bugden. Iris is adventurous and really just wants an adventure and to explore. One day Iris and Sam stubble upon a hidden and forgotten city. And definitely get an adventure. Well also trying to save their friendship.

Thoughts:
This book was good and I liked the plot of the story its adventurous and I liked the art in the book.
One part though that really sucked, personally (You don't need to read the spoiler to understand my thoughts on this book)

Spoiler

was that at the very end an older man that helps Iris and Sam through out the book has to tell Iris and Sam that both of them reminded him of his wife and him that started out as friends and then married each other. Something about this just annoyed me. Through out the book Iris and Sam are friends and honestly that part of the book was unneeded. I didn't find it cute or anything it was just awkward.

Besides that, it was a good book and I enjoyed the couple of last pages that tells you about the book and making this book and some history about cities or towns that are underwater in real life!
