Young adult nonfiction.  I have heard about the diminishing numbers of bee populations and have heard various theories about the cause.  This book talks not about one single cause but multiple intersecting causes.  Hirsch addresses habitat loss due to urbanization, climate change, fungus and parasites, and the use of pesticides.  She also discusses the commercial overseas bee trade and how that contributes.  A quick read that has solid information but doesn't get overly science-y.  Extensive back matter includes author's note, glossary, source notes, suggested additional books and websites, and an index.
