Keeper of the Bees — Amanda L. Webster

In this third and final book in the Valley of the Bees series, Valley's whole existence is in turmoil as she and all of her friends decide what they want to do with the rest of their lives. It seems like everyone except Valley is finding his or her own way in this fast-changing future world that has been struck so hard by the honeybee famines and the plague. Liam and Junior both demand that Valley choose which of them she will marry, and both of them want her to leave the farm and follow them to their new jobs. Meanwhile, Reyna leaves to follow her own calling. As if determining her entire future at the age of sixteen isn't hard enough, Valley also has her hands full with a mentally ill father who needs more help than she can provide. No matter what she decides, she will find that the future holds even more changes for a world that will come to depend on the well-being of Valley's honeybees in ways no one had ever imagined possible.
