Escape from Azkaban

My own "crossover" with a few new characters. Lilith a medi-witch from the states is brought into Azkaban to care for the hated DeathEaters when no one else will only to be inadvertently dragged into their escape. Will the men she's tried to help and actually sort of cares for turn on her or will they flat out kill her or will she turn to the dark side with them?
