The Telegraph provides fifty to avoid:
41 Courage by Gordon Brown: A tantalising prequel to the former PM’s future publications: “How to Get a Good Price for Your Gold”, “Debt Management for Dummies” and “Workplace Harmony”.
42 Jordan: Pushed to the Limit by Katie Price: Disappointingly thin on insights into the Hashemite Kingdom east of Israel.
43 Saturday by Ian McEwan: What the author learnt after spending two years getting in the way of a neurosurgeon. Not as good as Enduring Love, which is not as good as Amsterdam, which is not as good as Atonement.
44 Captain Corelli’s Mandolin by Louis de Bernières: Loved for its description of wartime Cephalonia, but now ruined by the constant appearance during civil partnership ceremonies of the passage about tree roots.
45 The Da Vinci Code by Dan Brown: Useful only as a shorthand to know whom to avoid on the Tube.
46 Twilight by Stephenie Meyer: See above, especially if they’re grown-ups, who really should not be fixating on vampires.
47 Harry Potter… by JK Rowling: See above, especially if they’re grown-ups reading a version with an adult cover.
48 One Day by David Nicholls: A wonderful book that follows a relationship over 20 years, spoilt only by people telling you how wonderful it is, while trying not to give away the ending (hint: very, very sad).
49 Scouting for Boys by Robert Baden-Powell: Awkward to ask for in a book shop.
50 Lolita by Vladimir Nabokov: Scouting for girls.
This list inspired me to come up with a list of six SF/F books you must not read.
