The Poison Jungle (Wings of Fire #13)

"Some secrets are deadly. It's no secret that Sundew wants to destroy HiveWings. It's her life's mission to exact revenge on the tribe that tried to wipe out the LeafWings and ripped every tree from the surface of Pantala. Every tree, that is, except those in the wild and dangerous Poison Jungle, where the surviving LeafWings have been hiding since the war--and waiting for a dragon like Sundew, who is uniquely qualified to bring down the hives. But secrets hide in the trees, too--some that Sundew is keeping, and some that she's only just beginning to discover. Now that a new war is upon them, Sundew and her friends must unearth the darkest mystery in the jungle--even if what they find has the power to destroy them all." --page [4] of cover
