Promised Land — Brian Stableford

In a galactic culture that extends from quasi-Utopian worlds like new Rome to vermin-infested slums like Old Earth, the Star-Pilots are the great heroes of the day, and Grainger has become a legend in his own time, flying the revolutionary ship, Hooded Swan. The rain forest of Chao Phrya seems a more hospitable place than the Halcyon Drift or the underground world of Rhapsody, scenes of Grainger's previous adventures. But the colonists of the jungle planet are crazed and the indigenous population enigmatic; and Grainger must must undertake a mission that requires a lengthy journey on foot through the dense forest. His quest seems awkward, hazardous, and doomed to failure--and that's before the giant spiders make their appearance! Hooded Swan, Book Three.
