I have just found a review of Conceit by Inkslinger on The Overdecorated Bookcase:
"To say I loved this book would not exactly be accurate. And yet, this is probably one of the best novels I've read in a long time. I preferred Humphreys' Afterimage, but Novik's novel has more depth and snaps the very bones of expectation."
Whether you like it or not it will certainly intrigue. Please read Inkslinger's review of Conceit and my review is here if you missed it.
EDITED TO ADD:
I am just pulling Inkslinger's remarks from the comments section up into this post, as I know not everyone reads the comments:
"I have to add that as time passed (and I read it a second time) my affection and respect for the novel only increased. Can't wait for her next novel! I hope both find their way to a UK publisher . . . "
This really is a seriously good book and with its London setting and metaphysical thoughts seems designed for the literary end of the UK market!
