Anna Karenina provides well a window into the rich diversity and complexity within human nature. Tolstoy, relentlessly rich in details, paints characters so deep and natural, that as a reader, I could relate with all the characters, at least in some way.
Their emotions and problems are real: Anna and her adulterous love affair with Vronsky, and Lenin, with his painful pursuit of purpose in this life. Oblonsky struggles to find substance in his "play-acted" life, and Kitty realizes only too late she spurned the man she truly loves. One could go on and on...so much life and human color is contained within the pages.
The novel is down to earth and beautifully written, and provides a wonderful depiction of 19th century Russia.
If you struggle in relationships, question God, or doubt the purpose of it all, this book is for you. I promise you'll find yourself in all the characters...I sure did.
