A novel by Spider Robinson, this tale concerns a time-traveler sent into the past on a mysterious mission, and whose plans are nearly undone by the fact that the first person she sees is a science fiction reader and thus immediately deduces what she is. Aside from being nicely recursive, it ties into one of Robinson's most famous works, Mindkiller... which could be looked at as both a curse and a blessing. It makes for a good extension of that posited in Mindkiller, but comes off as really not needed for the story, rather, it smells of a thrown-in plot point.

Regardless, it is an enjoyable enough sf read, though it is not his best work.
