...does this question not simultaneously fill readers with dread and excitement?
I hate it, because it's so vague. If someone asks "Can you suggest a good novel set in Egypt" or "Can you suggest a novel which has a delicious aura of rebellion" or "Something that has a really interesting main character"
These are more specific, therefore can be answered. One can file through their mental bookshelves and select an option or two that fulfill the request.
But to just pose any novel, from any time period, of any genre...give us a chance! There are millions of novels! Narrow it down a little!
At the same time, though, I also become an overly enthusiastic puppy, tale thumping and knocking over vases.
"Oh! I know one you'd like-oh, this one is good too! If you're looking for- oh, wait! Wait! I know the perfect one!...here, hold this..."
Soon, the poor unsuspecting individual is buried under a pile of books while I frolic around, chirping 'Just one more! You won't regret it!"
Moral of the story...if you ask a lit lover for a book suggestion, either narrow the category down so they can get a better idea of what you're looking for, or let them have their wicked way with you, and be prepared to be buried in a mountain of books.
