To prove that she belongs in a place where only the smartest and most useful are welcomed, twelve-year-old Yolanda learns that her survival rests on the rediscovery of a long-extinct beehive that could be the answer to everything.

In a future shaken by climate disasters, Yolanda Cicerón knows that nature is something to be feared. From the crops that don't grow to the terrifying creatures that roam the countryside, Yoly's life in the Valley is brutal and harsh.

But first, Yoly will need to prove she belongs in a place where only the smartest and most useful are welcomed. Between her razor-sharp smarts and sheer determination, Yoly is well on her way to leaving her farm life when she discovers her family can no longer afford her schooling. Desperate for a solution, Yoly is forced to take matters into her own hands, but the closer she gets to securing her future, the more she uncovers the dangers lying inside Silo's walls---ones that threaten the entire Valley.
