Deathworld

Deathworld centers on Jason dinAlt, a professional gambler who uses his somewhat erratic psionic abilities to tip the odds in his favor. He is challenged by a man named Kerk Pyrrus (who turns out to be the ambassador from the planet Pyrrus) to turn a large amount of money into an immense sum by gambling at a government-run casino. He succeeds and survives the planetary government's desperate efforts to steal back the money. In a fit of ennui, he decides to accompany Kerk to his home, despite being warned that it is the deadliest world ever colonized by humans...Deathworld!
