Bonsels' original book contains fewer than 200 pages. The storyline is centered on the relation of Maya and her many adventures.
Maya is a bee born in a bee hive during internal unrest: the hive is dividing itself into two new colonies. Maya is raised by her teacher, Mrs. Cassandra. Despite Mrs. Cassandra's warnings, Maya wants to explore the wide world and commits the unforgivable crime of leaving the hive. During her adventures, Maya, now in exile, befriends other insects and braves dangers with them. In the climax of the book, Maya is taken prisoner by hornets, the bees' sworn enemies.
Prisoner of the hornets, Maya learns of a hornet plan to attack her native hive. Maya is faced with the decision to either return to hive and suffer her due punishment, saving the hive, or leaving the plan unannounced, saving herself but destroying the hive. As may be expected, Maya, after severe pondering, makes the decision to return. In the hive, she announces the coming attack and is, totally unexpectedly, pardoned. The forewarned bees triumph over the hornet attack force. Maya, now a heroine of the hive, becomes a teacher, like Mrs. Cassandra and shares her experiences and wisdom with the future generation.
