The Android's Dream is a light and fun SF novel by John Scalzi.
A departure from the serious military SF in Scalzi's Old Man's War and The Ghost Brigades, this book is more in the vein of SF satire, and, in this fashion, is reminiscent at different points of early Neil Stephenson (Snow Crash) and Douglas Adams. As an example, the novel begins with an extended fart joke that runs through the entire first chapter. That's the kind of book this is.
Though not a perfect or substantive SF novel -- see Ranting Nerd's nice review of the book for a flushing out of some of the parts of the novel that may grate some readers -- it is a funny and entertaining novel and, in this sense, definitely succeeds.
