"The Graft Didn't Take"
I like reading lit from Austen's period, and I like science fiction. I thought this would be perfect! However, the author didn't take either genre seriously, and this sort of seemingly dashed off romp is too poorly executed to make it work. I can see how someone could enjoy it if they don't want subtlety and complexity...sort of like old style comic books.
Stick to reading Austen and Neal Stephenson alternately if you enjoy being immersed in another time and alternate realities.
