It is the subtitle that pertains here; the challenges in this book are fiendishly difficult. Walton has hosted BBC Radio 4's The Write Stuff, a literary quiz show, for more than a decade. This book contains ten quizzes, each consisting of five rounds, for which Walton provides annotated answers. The first, third, and fifth rounds are rapid-fire rounds, where a quick answer will suffice. The second round involves identifying extracts and their authors, and the fourth round is the most devious of all: given four literary people or things, the reader must tease out what links them. Although the book is based on the show, the knowledge required to navigate these quizzes is not solely based on British literature. A solid acquaintance with American literature is necessary, too, and children's and young adult books feature as well as adult works. VERDICT Those who wish to challenge themselves will find this an enjoyable read, but it calls for healthy arguments and group interaction. For this reason, it's especially recommended for book clubs or groups of literary friends. Be prepared to find that you know much less than you thought!—Audrey Snowden, Cleveland P.L.
