A complex, quirky time travel novella which takes place (mostly) at the end of time, after the Causality War has destroyed pretty much everything. The first person narrator – I'm not sure we ever learn his name – is a survivor of the war determined never to let it happen again, however-many people he has to kill if they find their way to his idyllic farm. He lives pretty well. Robots do most of the work, though he amuses himself by looting different time-streams for whatever he needs. If he gets lonely he simply gets into his own time machine and pops out to the 1700s for a party at Versailles or goes to see a Shakespeare play – with the Bard himself. His pet allosaurus, Miffly, helps him to dispose of errant time travellers. He also goes gadding around the timestreams putting an end to anyone who might contemplate time travel. Then one day, visitors arrive from the future. How can that be when he's already at the end of time itself? Weldon and Smantha (that's not a typo) come to viisit, and suddenly he has a problem. It seems he might be their many greats-grandfather. How is he going to avoid a second epochalypse? Funny and poignant in turns this is as sharp as a tack and well worth reading even though it chucks your logic circuits into a blender and serves them back up to you with a side order of wheee! I loved it.
