Years ago when I was pregnant with our firstborn and still "gainfully employed", one of my coworkers warned me that if I enjoyed books, I should cram in as much reading as I could before the baby came.  She declared that once her son was born, she couldn't find the time to read a single "grownup" book until he was in kindergarten.  Well, confirmed bookworm that I am, I soon found ways to fit in reading time here and there, like while nursing a sleepy baby, or at bedtime or while my babies were napping.  In this way, I have been able to read lots of great books.  The only ones I haven't been able to manage are of a type I used to read b.c. (before children):  classic literature with complex, old-fashioned prose and huge casts of characters.  For some reason, I have trouble keeping my mind focused on that stuff... (unless I am pregnant, and my mind is zinging along with lots of pregnancy/estrogen-fueled energy and alertness, and it's summertime, and there's nothing much else going on...)

Some of these books are out of print.  If they are not at your local library, you may be able to locate them through an out-of-print search service, such as at Barnes & Noble or amazon.com.)

Pride and Prejudice and Persuasion, Jane Austen.  Happily, the marvelous 1980 BBC version of Pride and Prejudice is now available on DVD - I highly recommend it. 

Jane Eyre, Shirley and Villette, Charlotte Brontë

Crime and Punishment, Fyodor Dostoyevsky.  This ranks right up there with the greatest novels I have ever read.  Dostoyevsky's penetrating insight into the mind of man is both deeply moving and profoundly unsettling.  Not to be missed.

The Brothers Karamazov, Fyodor Dostoyevsky - The greatest novel I've read;  many feel it's the greatest novel ever written.  Yet another work of deep psychological insight, it's wider in scope than Crime and Punishment, covering several broad themes while focusing on the superbly-drawn characters.  I read the Garnett translation, and I recommend this particular edition for Manuel Komroff's excellent foreword, "A Note about Dostoyevsky and a Key to His Work".  Garnett's translation is quite accessible but apparently not as accurate as the newer one by Pevear and Volokhonsky, which I also plan to read someday. 

War and Peace, Leo Tolstoy.  July 2004 - I am still wading my way through Tolstoy's epic, which I started a summer or two ago, and continue to dip into as time permits (I'm now over 3/4 of the way through).  The author moves deftly from intimate drawing-room scenes to the panorama of battle, with well-drawn characters who are by turns endearing, exasperating and occasionally (for me, anyway) baffling.  Unlike Dostoyevsky, Tolstoy seems less interested in plumbing the depths of human nature and more so in presenting his views on broad historical themes;  for example, do great leaders make history, or are they simply swept along by the unfolding of events?  The above-linked edition (translated by Aylmer and Louise Maude and edited by George Gibian) is the one to get, so I've read, both for its accuracy and for the helpful footnotes.  If you can't get enough of War and Peace, or if you're looking for a literature tie-in for your homeschool, check out Sergei Bondarchuk's award-winning film version.

Middlemarch, George Eliot.  Another one on my short list of "greatests".  Intricately woven, it's a rather slow (as in, worth savoring) and ultimately rewarding read.

Great Expectations, Little Dorritt and A Tale of Two Cities, Charles Dickens.  Our family greatly enjoyed the film version of Little Dorritt (Part One: Nobody's Fault and Part Two: Little Dorritt's Story), with wonderful performances by Sir Alec Guinness and Sir Derek Jacobi.

To Kill A Mockingbird, Harper Lee.  A 20th century classic.  If they didn't have you read this in high school, read it when you get a chance. 

Gulliver's Travels, Jonathan Swift.  Another family favorite:  the 1996 made-for-TV version starring Ted Danson and Mary Steenbergen, with a host of acting legends (Omar Sharif, Isabelle Huppert, Sir John Gielgud, others) portraying the colorful characters Gulliver meets on his travels.

The Scarlet Pimpernel, Baroness Orczy (more of a "lite" classic).  At last available on DVD, the excellent 1982 made-for-TV version (starring Anthony Andrews and Jane Seymour) is a treat not to be missed!

My favorite Bible version for readability is the New International Version, but I also love the Authorized or King James Version, and tend to remember Bible verses only as rendered in the KJV.  Makes it hard to find verses in the newer translations sometimes, when all I can think of is the Elizabethan wording à la KJV! 

There are scores of Bible versions out there, some more accurately translated than others.  Here are a few good resources for comparing the various Bible versions:

Why So Many Versions?
The King James Only Debate
Are there many versions of the Bible?  Or many translations?

The Keeper of the Bees, Gene Stratton Porter.  A lovely book, with memorable story and characters, and lush, evocative imagery.  This was one of my grandmother's favorites, and is one of mine as well.

Embrace the Serpent and The Campaign by Marilyn Tucker Quayle and Nancy Tucker Northcott - political thrillers with an authentic "Washington insider" feel and a decidedly conservative slant.  I read them out of order -- Embrace the Serpent is supposed to come first, but because it gives away the identity of the mastermind villain, readers following up with The Campaign may find themselves having a diminished reading experience.  I was fortunate to read The Campaign first, and not knowing who the villain was only added to the suspense.  In fact, the story was so gripping that I stayed up all night to finish it.  So if you want to read these, I recommend reading them out of order!

The Secret of the Rose series by Michael Phillips;  includes 4 books, The Eleventh Hour, A Rose Remembered, Escape to Freedom, Dawn of Liberty.  Outstanding series, beautifully-written, moving and insightful.  Worth multiple readings to glean all the wisdom the author has woven into these books, which take place in and around Germany during WWII and the postwar/Cold War period.

A Rift in Time and Hidden in Time by Michael Phillips - searching for Biblical relics in the last days.  I liked Rift in Time the best of the two, but they're both very good.
