| Ender was Wiggin's nickname, and gives the answer away-- particularly if you don't accept the other books in which he was the protagonist. Andrew Wiggin would be the better clue, but more important-- as @Babamots said-- is to include at least Speaker for the Dead, and probably the other two, as alternate answers.
And consider at least hidden-answering Paulo Coelho's The Alchemist, the protagonist of which was also named Santiago, rather than having two Hemingway novels on this short list. |
