I love this thread!
From childhood: the Sadlers Wells series - I must have read them twenty times or more each. And Katherine by Anya Seton (read 10 times?) And yy to Summer of My German Soldier and The L-Shaped Room.
Adult novels: yy to Atonement, Poisonwood Bible, anything by Atwood, anything by Yates but especially Revolutionary Road and Easter Parade, We Need to Talk About Kevin, I Capture the Castle,.
Some not mentioned yet (or only other books by the same author):
The Colour (Tremain), Paradise and Song of Solomon (Morrison), The Outcast (Sadie Jones), Corrections (Franzen), Oscar and Lucinda (Carey), all of Alice Munro's short stories, all of Margaret Laurence's Manawaka series, The Crimson Petal and the White (Faber), Underworld by Don DeLillo, My Brilliant Career by Miles Franklin, Katherine by Anya Seton.
Ooh, I could go on forever - but those are the ones I've read at least three times and are old friends but make me sad I won't ever read them again for the first time.
I love everything I've read by Rose Tremain but haven't read her historical novels - I'm not usually a huge fan (except for Katherine!) - but I will definitely give Restoration a go after this thread.
Thanks!
