Bill, the Galactic Hero on the Planet of Bottled Brains (BtGH:PoBB) is a novel by Harry Harrison and Robert Sheckley, published in 1990.
After Sheckley's initial collaboration with Harrison in 1990, the following year four additional novels in the series were released, all with Harrison as co-author, most with the same Bill, the Galactic Hero on the Planet of... titles, but involving differing collaborators: Tasteless Pleasure with David Bischoff, Zombie Vampires with Jack C. Haldeman, Ten Thousand Bars with Bischoff again, and finally Bill the Galactic Hero: The Final Incoherent Adventure with David Harris.
[o] PoBB is about the continued adventures of the protagonist Bill, in extraterrestrial universe involving faster-than-light space travel.
A review by David Langford was largely negative, noting that many of Sheckley's long-running themes were found in PoBB—humor, abrupt literary transitions, malfunctioning computers, and philosophical digressions—but calling the implementation of those recurring thematic elements in PoBB "pale echos of... the remembered sparkle" generated by Scheckley's previous works.
