The first third of this chatty guide to modern and classic adult fiction is a series of essays recommending key authors and titles in 34 various genres/topics/national literatures. Each is written by a writer or editor (mostly British) with "a special interest" in the the subject, although very few are household names (the two most well known are probably crime writers Michael Didbin and Val McDermid). The essays are about four or five pages, and include a "Top 12" list of the essayist's favorites in that area. While these are somewhat fun to dip into, like all such essays they are awfully idiosyncratic, and thus need to be taken with many grains of salt.
Nonetheless, the editors should be commended for highlighting a good deal of world literature, with essays devoted to: Africa, Australia/New Zealand, Canada, The Caribbean, France, Germany, India, Ireland, Russia, and the U.S. However, other than this particular coverage, readers should be aware that the authors and titles selected for mention have a very strong British emphasis. Authors were only included if they are well-known (in Britain), in print, or seminal to a particular topic or genre. However, while most selections may be available in the UK, some may be much harder to track down elsewhere.
The remaining two-thirds of the book are small biographies of 1,000+ authors, with indications as to their key works, and three "similar" writers. For example, if you like Nick Hornby, try Roddy Doyle, Kingsly Amis, or J.D. Salinger. On the whole, an attractive, accessible book to dip into to get some ideas of new stuff to read, but hardly the last word on the topic.
