The 20th anniversary edition of the classic steampunk novel
With new commentary by the authors
1855: The Industrial Revolution is in full swing, powered by steam-driven cybernetic Engines. Charles Babbage perfects his Analytical Engine, and the computer age arrives a century ahead of its time. Three extraordinary characters race toward a rendezvous with the future: Sybil Gerard--fallen woman, politician's tart, daughter of a Luddite agitator; Edward "Leviathan" Mallory--explorer and paleontologist; Laurence Oliphant--diplomat, mystic, and spy. Their adventure begins with the discovery of a box of punched Engine cards of unknown origin and purpose. Cards someone wants badly enough to kill for.

Part detective story, part historical thriller, The Difference Engine took the science fiction community by storm when it was first published twenty years ago. This special anniversary edition features an Introduction by Cory Doctorow and a collaborative essay from the authors looking back on their creation. Provocative, compelling, intensely imagined, this novel is poised to impress a whole new generation.

I would buy this twice!
Style: Sport, Size: 12in
This Chuckit! Dog Ball Launcher 12M Sport is the perfect product for the dog park! It makes games of fetch so much easier and more fun — the long handle gives great reach, so I can launch balls super far without even bending over, and our dog goes absolutely wild chasing them. It’s comfortable to hold, works smoothly with 2.5" dog balls, and really saves your arm and back if you’re doing a lot of throwing. The design is sturdy and reliable, so we can play for longer without worrying about it snapping or wearing out. If you spend time at the dog park or love playing fetch, this launcher turns a regular game into something even better — our pup gets twice the exercise and we get to enjoy every minute of playtime!

Caution can cause addiction
Style: Sport, Size: 12in
My dog has become addicted to tennis balls because of this! She sees the blue handle and she immediately loses her mind! I love it because I don't have to bend down as far to pick up the ball, which is amazing after 2 back surgeries.

12 " too short, no direction.
Style: Sport, Size: 12in
I got the twelve inch handle. It is too short and does not flex enough to release ball in right direction. Its almost impossible to aim and doesn't sent the ball far enough.

Great for heavy chewers! Belgian Malinois Approved!
Color: E) 8-Pack 2.5" Balls (Yellow)
I bought these 6 months ago because my dog kept loosing his Kong balls. These were such a better price ball (but still had good reviews) that I thought I would give them a try. They are wonderful. After six months of chewing and chasing and playing with a Belgian Malinois, the two that I’ve gotten out are still in great condition. The bright color makes them easier to find, so none have been permanently lost yet. They are bouncier and a little bit lighter weight compared to the Kong balls of the same size, which I honestly appreciate because my maligator likes to shoot them at my feet. So far the material seems high quality and I feel safe letting the dog chew on it for hours on end. The 8 pack was cheaper than 2 Kong balls. A great deal for a great product!!
