From Zeonic Republic:
Universal Century 0093. Char Aznable, once lost to the world, has risen from the shadows to revive the Neo Zeon forces. Turning a blind eye to the pleas of the space colonists, the Earth Federation government wallows in its terrestrial indolence. Char, ever audacious, wages a war against them, hatching a plan to hurl an asteroid at Earth, altering its climate, and triggering an artificial Ice Age. The consequences would not only render Earth uninhabitable but also subject countless innocent lives to brutal purging at Char’s hand! Amuro Ray, Char’s age-old rival, dares to stand against this grand design. Behold the spectacle of unparalleled proportions in the history of animated storytelling: the original narrative of “Mobile Suit Gundam: Char’s Counterattack” makes its triumphant debut.

The original storyline proposed by Tomino for the Mobile Suit Gundam: Char's Counterattack movie was rejected and released as this novel. Both Beltorchika's Children and Char's Counterattack are based on Kidou Senshi Gundam High-Streamer (Novel) with notable differences.
