Daisy Bell

A strange voice forces its way into a young woman's head the day she turns eighteen. He tells her that she can touch the stars, transcend humanity, if she jumps off a cliff. He says that he created her world.

The scariest part is that he's telling the truth.
After she wakes up in a different world with a new body and a controlling captor who thinks himself a god, she is forced under the public spotlight as a marvel of science-- a spectacle. Determined to find a way back to her home universe, she must unravel all of his secrets or die trying.
He wove her universe. She got caught in his web. Now she must escape.
