Blue the SilkWing is content. Life in his Hive is safe, he loves his family, and he has enough to eat. And Pantala has been at peace for as long as he can remember. SilkWings and HiveWings live and work together in harmony, and because they stay vigilant, no one has seen a dangerous LeafWing in years.

Now that Blue’s sister, Luna, is undergoing her Metamorphosis, Blue knows things are going to change. Luna will have her wings and her silk, be assigned a partner and a work order, and move to another Hive. A few days later, Blue’s own wings and silk will come in.

But no one could predict what happens when Luna’s wings start to grow. Pantala isn’t as peaceful as it seems, and Blue faces the ultimate challenge: adapt to the change—or die!
