This synopsis is from The Looking Glass Wars website. You really need to visit and watch the trailers, look at the imagination gallery, etc.
"The Looking Glass Wars unabashedly challenges the world’s Carrollian Wonderland assumptions of tea parties, dormice and a curious little blonde girl to reveal an epic, cross dimensional saga of love, murder, betrayal, revenge and the endless war for Imagination. Meet the heroic, passionate, monstrous, vengeful denizens of this parallel world as they battle each other with AD-52’s and orb generators, navigate the Crystal Continuum, bet on jabberwock fights and slip each other the poisonous pink mushroom. Finally, someone got it right. This ain’t no fairytale.
Alyss Heart, heir to the Wonderland throne, was forced to flee through the Pool of Tears after a bloody palace coup staged by the murderous Redd shattered her world. Lost and alone in Victorian London, Alyss is befriended by an aspiring author to whom she tells the surreal, violent, heartbreaking story of her young life only to see it published as the nonsensical children’s sojourn Alice in Wonderland. Alyss had trusted Lewis Carroll to tell the truth so that someone, somewhere would find her and bring her home.
But Carroll had got it all wrong. He even misspelled her name! If not for the intrepid Hatter Madigan, a member of the Millinery (Wonderland’s security force) who after a 13 year search eventually tracked Alyss to London, she may have become just another society woman sipping tea in a too-tight bodice instead of returning to Wonderland to battle Redd for her rightful place as the Queen of Hearts."
