Pip likes salt, and when Flinx is in the credit, he buys a big bowl of giant pretzels ... Pip gets in the bowl and rolls around in them, eating. I love that image!
Check out his other stuff, too, especially the books featuring September Skua ... they are an offshoot of the Flinx books. Also check out Montezuma Strip and The Mocking Program ... police procedurals set in the future, with harder science than J. D. Robb's Death series.
Did Da Bear recommend the Peter Hamilton books?
