In 1980s Washington state, Mt. St. Helens is rumbling. Twelve-year-old
Maribel isn't concerned at first, despite officials evacuating her
neighborhood. Her family is convinced it's just a precaution, even as
the mountain continues to rumble. Maribel decides to disobey orders and
return home for items she and her sister left behind - just as the
volcano finally erupts. As ash rains down, Maribel realizes she must
learn to focus if she's going to survive.
