Surfacing

Read a cool book.

Surfacing by Andrew Scott Turner.

The setting is an underground civilization about two hundred years from now. The people retreated from America as the self-destruct commenced. As the decades passed, they went deeper until the time when our story takes place.
I loved the young female protagonist. She's as fiery as I hope I'm raising mine to be. She's a swimmer, like I was at her age. (Undefeated! Go Marlins!)
Really, it deserves a good critique. It harks back to the Hollow Earth stories of a century ago. It inverts the post-colonial thrust because the protagonist is driven to ascend for her encounter with the society her people left behind.
Stay tuned.
