Favorite book?!? I can't choose just one, that way lies madness.
So I'll just do a few quotes from my favorite 5-star books:
“It is said that your life flashes before your eyes just before you die. That is true, it's called Life.”
― Terry Pratchett, The Last Continent
“In a child's eyes, a mother is a goddess. She can be glorious or terrible, benevolent or filled with wrath, but she commands love either way. I am convinced that this is the greatest power in the universe.”
― N.K. Jemisin, The Hundred Thousand Kingdoms
“Miss Tarabotti was not one of life's milk-water misses--in fact, quite the opposite. Many a gentleman had likened his first meeting with her to downing a very strong cognac when one was expecting to imbibe fruit juice--that is to say, startling and apt to leave one with a distinct burning sensation.”
― Gail Carriger, Soulless
