Can anyone explain this, technically or otherwise? If you search for <“The Eagle of the Ninth” +Sutcliff> on Google books, there are four ‘related books”:

• Three Men in a Boat by Jerome K Jerome
• The Big Sleep by Raymond Chandler
• Gulliver’s Travels by Jonathan Swift
• Little Women by Louisa May Alcott

Good books all in their different ways; and Rosemary is keeping fine company! But why these four, and not some of her other books, let alone some closer relatives like historical fiction …..
