So Aliya's given up on Wolf Hall. Like she says, she's not usually a quitter.
I managed to get through One Hundred Years of Solitude and Lark Rise to Candleord and am glad I made it, but I did abandon Le Carre's The Naive And Sentimental Lover to the whimsy of the London Transport system, and have been put off reading any more of his work. And David Hebblethwaite has just convinced me to steer clear of Oryx & Crake and The Year of the Flood by damning them with faint praise. There are scores of other similarly abandoned and never reads littering my past. But maybe I should have persevered with some (Do I really need to read Tender is the Night? The writing is beautiful but the characters--muh.) and not bothered to finish some of the others--I'm looking at you Richard Beard's The Cartoonist.
What books have you wasted time on--and wish you hadn't--and are there any you started, but didn't finish, but have a niggling suspicion maybe you should have?
