Wings of fire ; book 13
Sundew, and most of the other LeafWings are nursing a deep hatred for the HiveWings, who have ripped every tree from the surface of Pantala, except those in Poison Jungle where the surviving LeafWings have been hiding, waiting for a dragon clever and powerful enough to exact their revenge--and now they are searching for the jungle's oldest and darkest mystery, one that could destroy them all.
