Geneva Hastings is a bounty hunter from the Human Polity (a rather excellent series by Neal Asher). She and her passenger end up on a world that is strangely familiar, yet utterly bizarre; Earth Bet, as of 2011, in the Wormverse. Things are going to get interesting ...
Janesha of Mystal is a celestial. Not yet a god in her own right, she has managed to irritate one, and has gone on a self-imposed journey of discovery that ends up in an unexpected side-trip ... to a place called Brockton Bay.
Just when Taylor feels she's getting in over her head with Lung, a strange visitor from another world changes everything. (This is a crossover of Worm and a novel I am in the process of writing.)
Jimmy ended up on the streets of Brockton Bay, a city filled with parahuman gangs, after the death of his parents, but it beat ending up in the system as far as he was concerned. Now all he had to do was keep himself clothed, fed, and pass his GED when he turned 18. Piece of cake, right?
