Firefly Ghost Machine Hardcover

" Mal and the crew take receipt of a sealed crate which they are being paid to transport to Badger, no questions asked. Yet once their cargo is safely stowed aboard, River insists Mal should 'space' it out of the airlock, for it contains, she insists, ghosts. The crew desperately need another pay day, but soon find themselves paralysed by hallucinations of their deepest hopes and desires, so vivid they cannot be distinguished from reality."
