Kate Gallagher and the Bexus Prophecy

She stopped and raised the torch. Kate looked. Alone on the wall was the figure of a girl with ice blue eyes and skin that glowed with a pure golden aura, standing out like an island in a dark black lagoon. ...
There was no mistaking the identity of the tiny figure. Kate was staring at her own image burned into the wall.
Bexus is another world, a hostile world of magic, adventure, and tremendous danger, and there's only one way to get there-die. Neither heaven nor hell, Bexus is a world where the souls of the dead get a second chance.
When Kate Gallagher awakens in Bexus after she is killed in a train wreck, she finds that her soul has retained a powerful memory of her earthly form. She also finds she bears a very dangerous mark-a golden aura that indicates purity and possibly the fulfilment of a prophecy. Kate finds herself chosen and suddenly thrust into the middle of a conflict she cannot hope to survive. With nowhere to turn and an entire world counting on her, Kate has no choice but to set out to fulfil her destiny.
But Kate and her new friends are not the only ones who know of the prophecy that foretold her arrival. Varak, the tyrant lord of Bexus, is well aware of what her coming could mean for him. He's determined to capture and kill Kate before she can fulfil her destiny and return peace to Bexus.
