The Dam Keeper by Robert Kondo; Dice Tsutsumi

This story is a bit sci fi and all fantasy.  A young pig is the Dam Keeper now, since his father went into the unknown.  There is a fog that approaches the city and only their windmill can hold it back with the help of the dam.  He does what he learned.  But then the fog changes...

First Second Books and Net Galley let me read this graphic novel for review (thank you).  It will be published September 26th.

Pig is alone.  His mother died, his father went insane, and he has almost no friends at school.  Fox is nice to him but she's friends with Hippo who is not.  When Fox comes to visit and brings Hippo, he's not happy but he tries to be nice.  Suddenly the fog is moving when it shouldn't be and the dam breaches!  They run from the falling structures and find themselves outside the walls...

There is plenty of adventure, odd creatures, and another city there.  They just want to go home but they're not sure how to get there.  Perhaps someone in the city will help them.

This is the first in a series and it's interesting enough to keep me reading.  I want to know if Pig finds his father and how he, Fox, and Hippo survive.  Wouldn't you?
