This book is a collection of the first through third books of the Beesong Chronicles series:
Sting & Song,
Webs & Wards, and
Hives & Heroism.
Joy was a giant bee. She never expected to be anything else, but then the god of chaos transformed her hive and many others into the apis, human-like bee-girls. Exiled from her hive, Joy found new friends who could explain the mysterious system that governed those who weren't monsters and who were willing to help her enjoy her new life.
When they stumble into a plot to destroy their kingdom by a demon, Joy throws herself into the adventure with enthusiasm, ignoring her own short lifespan. She may be only one apis, but she would gladly give her life to protect her personal hive, and if she manages to survive? So much the better.
