X Files YA #09 Hungry Ghosts (X Files YA, 9)

It is Yu Lan in San Francisco's Chinatown, the Festival of the Hungry Ghosts -- a time of year when offerings are made to appease the ghosts roaming the earth. Only this time several murders have occurred, and the last victim left behind one message: the Chinese character meaning ghost. Locals fear that perhaps the Hungry Ghosts have not been appeased, and are seeking revenge. But when Special Agents Mulder and Scully are asked to investigate, they stumble upon a deadly lottery run by a secret society of Chinese immigrants. The winner receives a large sum of money -- but the cost of losing could mean death.
