@KronshiOh god brownies sound good...why did you say brownies? hmmm
Anyway, basically it was about Alice returning to the real world (I think after multiple trips and or disappearances) and being locked in an mental hospital by her father who is a lead doctor there. Alice tells her story of Wonderland to the other patients who all suffer from one sort of illness or another. They listen to this, it is an interesting little story but even they do not believe her but Alice warns them that they better believe because a portal is coming.
Once the portal opens, a select few get sucked in along with Alice's father to Wonderland but it isn't the beautiful story Alice had told. All of it was a lie sprinkled with partial/barely truths. Worse yet, Alice is not the hero of this tale but the villain as she is the reason for Wonderland's despair. Those with illnesses gain powers in Wonderland, each one connected to the illness they have in the real world. Suddenly, the real world weakness is now the greatest of strengths. They must find Alice, stop her and bring Wonderland to peace but it will not be easy with everything and everyone against them. Fear is a dark thing.
