Hoo boy, I love too many books to have just ONE favorite, so here’s a few from near the top of the list….
'The Virginian' by Owen Wister. I fell in love with this book a few years ago and it’s definitely a favorite; it’s a great western novel from before they became a cliche, I love the writing style, and I just now realized that I’m overdue for a reread.
'The Man Who Was Thursday' and 'Manalive' by GK Chesterton. Anyone who has asked me this question in the past several years has received these two titles as an answer. I honestly can’t describe these books, except to say that they are some of the best books I’ve ever read.
I recently bought and fell in love with ‘The Book Thief.' I read it twice in the past couple months, and actually cried harder at the ending the second time than I did the first.
The Attolia Series by Megan Whalen Turner is awesome. The third book is my personal favorite. The second book starts out horribly depressing, but it’s amazing by the end.
And last, but most definitely not least, the Narnia Series by C.S. Lewis. I didn’t grow up on these books like some of the fans did, but they’ve still been a huge part of my life for the past eight years and I’ve reread them more times than I can count. Love them more than I can say.
EDIT: forgot to mention 'Do Butlers Burgle Banks?'! If you enjoy humorous books then you can pretty much do no wrong with Wodehouse (though sometimes a little can go a long way), and this one is undoubtedly my favorite that I’ve read of his.
