Skipper and Sam are back, four years after they vanquished Odoursin and saved humankind from his terrifying plans. But the Aurobon they return to is vastly different from the one they left. Vahlzi has been destroyed and all that remains of Firebrand's forces are scattered groups of resistance fighters. For after his defeat, Odoursin went underground, waiting until the time was right to unleash his new army and annihilate Vahlzi for good.

Filled with grief and rage, Skipper and Sam are determined to help their surviving friends fight Odoursin and build a squadron of the fiercest insects ever seen. But their mission becomes heart-stoppingly urgent when they discover that Odoursin is once again plotting to destroy humankind - this time by using the President of the United States . . .

An action-packed adventure of good versus evil, wisdom versus greed - bursting with danger, heroism and ferocious insects.
