The Once and Future TH White
This book is in my lifetime top ten list. I've read it three times. Its pages are full of wisdom, humor, mysticism and hard life, an unbeatable combination. I call the story "a hopeful tragedy." For sure it is a high tragedy up to Greek levels and then some. And yet it's hopefulness lies in King Arthur's ability to continue deepening, learning, reaching for the goodness that he still believes is in every person.
Someone said that The Once and Future King was the "Harry Potter" of its day. While I love the Harry Potter series, Rowling is no T.H. White. Her writing is a serviceable yeoman's march compared with White's kingly, profound, sometimes soaring performance. Harry changes very little as he grows up, while his supporting characters seem to stay exactly the same. Not so with Arthur. He changes before our very eyes, sometimes not for the better, as does Lancelot, Guinever and others. Though both tales are mythological, White's story feels real and gets us deep down in the bowels of our conscience, our morality and our fears. Eventually, it provokes compassion, allowing us to become more forgiving of ourselves and others. Not a bad way to live in the world. When you really learn something, you become a different person. You will really learn something from The Once and Future King, making T.H. the Once and Future White.

Not what I expected
Format: Mass Market Paperback
I love stories about King Arthur and that time period in general. I really looked forward to this book because of the high ratings and my special interest in the subject. There was a lot to like about the book. The author was imaginative and, at times, the writing and characters came alive.
I have to say sometimes it was kind of like riding in an old car over a road filled with pot holes -- I kept getting shook out of the story by either references to things not from that time period or the endless social commentary that seemed to be the real point in the author writing the story. By about halfway I was wondering why he didn't give up on the story and just write a philosophy book. He wasn't being subtle. I just wanted to get back to the action and felt like I was being preached at through the narrator and the characters. I also love historical details but be aware that this author tends to mention armor and then go on and on for a while to explain it down to the tiniest detail - same with jousting - the details of what the men are wearing as fashion - what is hanging in the room - and so on.
As for the characters, it was sad to see Arthur diminish to being almost a shadow or joke near the end. The glorious king who was supposed to be so strong appeared to have no power to do anything and even allowed himself to have no voice in his own court (Gawaine did the talking). He didn't have any real presence after the very beginning though - not even as a tragic character until the very end. The author didn't make him feel like a real person in what is supposed to be his story. Arthur is the shadow between Lancelot and Gwen (or Jenny), Arthur is the go-between for the vengeful knights in his failing efforts to keep peace... He stands back hoping something will happen to stop the burning of his wife... he is not instigating but moderating action. He is even described as plain, shuffling... Not the grand King Arthur.
Merlyn was a joke as well. His magic was more like a Disney cartoon special than anything resembling Arthurian legend and the constant references to things from the future (or Merlyn's past if you buy him living backwards) kept yanking me out of the "story world" and the other characters almost never reacted to it - as if it were normal. He leaves soon after Arthur becomes king and never comes back (you know the whole locked in the cave thing).
The character most fleshed out is Lancelot. The author spends a great deal of time into his motives, feelings and actions through almost the entire book. If it weren't for the very beginning, you might be able to make an argument that more is written of Lancelot than of Arthur. Lancelot seems stronger, more driven and more clearly defined nearly at all times in the book. You know what he wants and how far he'll go to get it.
In the end I am glad I read it, but it isn't my favorite Arthurian book and I doubt I'll read it again.

A challenging read
Every now and then I challenge myself with a classic. This one was definitely that - a challenge. Allow me to explain.
First, this is the story of King Arthur. All the characters are present: Gweniviere, Lancelot, Merlin, the Knights of the Round Table, the sword in the stone, Mordred, and all the ones I’d ever heard of in retellings-of the story. However, many were not as good, bad, beautiful, handsome, or courageous and pure of heart as I’d been led to imagine. These characters were messy and deep with honor and dishonor battling within them. But there was a quiet strength and desire to do good about them. So, this book challenged my preconceived images of these characters.
Second, this book is long. It is divided into four parts. The first two parts were more familiar (maybe) and were a little easier to read. They told of Arthur’s early education under Merlin, pulling the sword from the stone, and establishing the Round Table - the glory days. Part three tackles the love triangle between Arthur, a Gwen, and Lancelot; the quest for the Holy Grail; and the rise of Mordred. Part four got a little tedious describing the fall of Arthur’s reign, the destructive force of lies and secrets, and the power of evil. This section challenged me with some very deep theological and philosophical musings amid the battles among friends and family.
Finally, this book is written using a Middle English wordings and geographic dialect. I had to look up many words (not all definitions could be found) to really understand some things, but was generally able to follow the story. The author also frequently talked directly to the reader which took some getting used to. The writing style definitely challenged my vocabulary and ability to follow transitions from author speaking to characters.
One last thing, the ending was left somewhat open to interpretation and imagination. I choose to believe the happiest of the possible outcomes. I’m glad I read this book, but i think I’ll go read something a little easier next!

Freshest breathe
I recently purchased a stainless steel tongue cleaner, and I am pleased to report that it is a great product. The cleaner is made of high-quality stainless steel, which is extremely durable and will not corrode over time. It is also easy to use and clean, as the cleaning part is made of a smooth and rounded end that fits comfortably in my mouth.
The cleaner is also very effective at removing bacteria and food particles from my tongue. After using the cleaner for a few days, I noticed that my breath had improved significantly and that my taste buds were more sensitive. I was also surprised to find that the cleaner was gentle enough to use on an everyday basis without causing any irritation.
Overall, I am very happy with my purchase and would highly recommend it to anyone looking for an effective and affordable tongue cleaner. Not only is the stainless steel cleaner effective and easy to use, but it also lasts longer than other tongue cleaners on the market. I would definitely recommend this product to anyone looking for an effective and reliable tongue cleaner.
