From the Guardian‘s Books Blog:
There are certain turns of phrase in the modern reviewers’ arsenal that are guaranteed to turn the stomach of any reader. It is these descriptions that are then shoved on a dust jacket or printed on a giant advertising board slotted on the wall of a London tube station. “Unputdownable” is one: a Germanic agglomerate of a verb, an adverb, an adjectival ending and a privative prefix that bring to mind some indomitable hardback with springs wired into its spine. No matter how many times you throw it away – angrily at first, then in desperate terror – it always bounces back to smack you on the nose.
(He also doesn’t like it when people write, “This book will change your life.”)
