"Princess Marya had experienced the best happiness of her life. Her love for Rostov no longer worried or upset her. That love filled her soul, became an inalienable part of her, and she no longer fought against it. Most recently, Princess Marya had become convinced -- though she never said it definitely to herself in clear terms -- that she loved and was loved."
Finally! After all the emotional abuse doled out by her cranky father.
And another bit I like:
"As always happens during a journey, Princess Marya thought only about the journey itself, forgetting its goal."
That's kind of like this whole project -- enjoying the journey. Which we've been on for 2 years now! -- Lola
