The Eyre Affair
by Jasper Fforde
Grrr. Makes me mad.
"I'm a rough, tough girl detective. The only thing I want more than my suspect dead to rights is to be pregnant and to wash dishes." and what not.

Apparently Tycho over at Penny-Arcade liked it.

"The Eyre Affair, apparently a part of some larger series, is sci-fi of such a constrained genre that I wasn't even aware it existed: romantic, literary sci-fi, for people who like stories about time travel, alternate universes, and classic literature where the protagonist gets married at the end."
