I picked this up on a friend's recommendation and I'm very glad I did; it was really quite excellent.
Charlie's husband tells her out of the blue one morning that he's started divorce proceedings. Shortly thereafter, his obnoxious best friend tries to feel her up, and she accidentally kills him. This does not, I grant, sound like a promising opening. But the author manages to make it brilliantly funny. Charlie goes back to her family home in Yorkshire, currently inhabited by her father (a literary biographer who specialises in "proving" that women's writings were really done by the men in their lives), her father's mistress (plus awful offspring), her sister Emily (domesticated, outspoken, and a witch), her sister Anne (a war correspondent, home temporarily after cancer treatment), her brother Branwell (an academic of excessive eccentricity), and the Loyal Family Retainers, Gloria and Walter.
And then there are various people falling in love, and such diversions as melon-bashing, searches for shallow graves, paternity testing, magazine production, and witchcraft. And a collective happy ending.
The characters are all lovely (except the ones who aren't meant to be, obviously, but even they have life and personality), Charlie (who is also the narrator) has a most engaging voice, the various story strands braid beautifully together, and the whole thing is laugh-out-loud funny (I think I scared some people on the bus, giggling at it).
And how can you not love a heroine who guesses that her now ex-husband's promises of generosity in maintenance are likely "to dwindle away, like in Sense and Sensibility [...] where the widow and her daughters were going to be looked after by the son who inherited everything, only the allowance sort of dwindled away to the present of the odd duck". ("The odd duck" subsequently becomes a catchphrase throughout the book, and made me giggle every time.)
