Eleven-year-old Shayna Miller lives in the Subterran world where people hide from the totalitarian government that rules topside. But her dad keeps moving their family from place to place, almost as if he's running from something in Subterra itself. But what? This book is set in the same time and region as The Birdwatcher, with which it shares a few characters. Other books in The Smolder series - but set in different locations with different characters - are The Smolder, The Hidden, and Notes From Hiding. This book was originally published in 2013. This is the 2015 slightly revised edition.
