Bill, the galactic hero on the planet of robot slaves

Bill would give his right arm to defend his Emperor against the alien Chingers - which is lucky seeing as he has two of them...War demands sacrifices, and if you've lost one left arm, have an artificial foot and a set of nifty surgically-implanted tusks, it's a small price to pay for the privilege of being a hero. And Bill knows all about heroism - as part of a motley crew his new task is to track down the source of Chinger-controlled metal dragons that are making mincemeat out of humans. A sequel to the author's "Bill, the Galactic Hero", published over 20 years ago, this book is the first of a new series of novels featuring Bill. With two right arms, an artificial foot and a set of surgically-implanted tusks, Bill sets out to find the source of Chinger-controlled metal dragons. This is another "Bill, the Galactic Hero" book. It's chock full of puns, satire and utter nonsense that breaches the bounds of sanity - who has to throw it all back to survive. It's a fun read, though you may need counseling after you finish reading it.
