This was my first read of a Lauren Oliver book. It was obvious after the first few pages that it was extremely well written, and that there was a special - one might say ineffable - quality about the writing. 
 All of the great books have a special quality in their prose. But there was something about this one that just radiated warmth. The phrases and pages had a symphonic quality as they wound around my head - a sort of perfection of timing and tone, of musical phrases moving separately and then coming together. 
 I kept thinking, as I read, about just what it was that made the book so magical for me. After all, this was a "children's book", and I had bought it for my my two grade-school-age boys. I did that because of glowing reviews from GR friends that I trust implicitly, including those from Wendy and Kaethe. As I have said before, it is extremely easy to find the best books to read when you rely on advice from those who REALLY know books, and have read (seemingly) EVERYTHING. 
 Well, of course our boys were too busy destroying intergalactic aliens on the Wii, DS, computer, etc. to be bothered until 'later' with any book that I recommended. Especially when I hadn't read it, and especially when there were Big Nate and Wimpy Kid books lying around handy - known and trusted sources for boy-humor. (I get nightly Big Nate passages read to me by the younger one, when he is supposed to be asleep) 
 So, I picked a propitious moment to tag along with my friend Cillian and read this book. And promptly fell in love with it. 
 Liesl is a lovely little girl who has been locked away by an evil force in her life. Living in miserable conditions, she grieves for a lost loved one. When Po appears, her life begins to change. 
 "...Po wasn't exactly sure why it had appeared in Liesl's room... Over the past few months Po had seen a dim light appear at the edges of its consciousness at the same time every night, and next to that light was a living one, a girl; and in in the glow of that light the living girl made drawings." 
 As each new character is introduced, we get a fascinating thumbnail of the personality, but little idea of how the pieces will fit. 
 "...a very frazzled-looking alchemist's apprentice was standing on the quiet street in front of her house, staring up at her darkened window and feeling sorry for himself." 
 "Pathetic, the alchemist would say. Worse than useless. As ridiculous and deluded as a frog trying to turn into a flower petal..." 
 The potions and magical elements start to appear. And the story begins to take shape around a small wooden box and an unfortunate (and portentous) mistake. 
 What follows is a series of highly fortunate, and then most unfortunate coincidences. And if you are like me, you are not bothered at this point by trivialities such as probables and plausibles. After all, the bending of realities is not sooo egregious, and the elements of fantasy are so beautifully delivered that every piece seems to fit exactly in its proper place. Even the evil ones are deliciously bad, and the whole structure moves forward with a sublime rhythm that I found completely mesmerizing. 
 "Augusta produced a large golden key from her purse, and with it unlocked the gates. She gestured grandly for the Lady Premiere to precede her into the yard. Inwardly, Augusta trembled with excitement. A visit! From the Lady Premiere! Who was a princess in her native Spain (or was it Portugal...?)! It was outstanding! It was unheard of! The neighbors would seethe with jealousy." 
 The plot lines cross and re-cross, and this magical story winds along, with all of its twists and turns. The prose is superb throughout. Every step of the way, you get a clear (3rd person) picture of the thought processes in each of the characters. 
 For me, this book succeeds at every level. I was particularly pleased with the treatment of the good-vs.-evil themes and characters. It is easy to look around us and see evildoers (use your own definition) who succeed beyond any notion of 'justice', and to conclude that there is no justice in this life. But if you observe carefully, you can often find examples where evil is its own undoing. And every now and then, you can give a little boost to the process and speed things up just a bit. If you think about how that happens, you might just find some of the same elements at work in this tale. 
 I felt a wonderful sense of calm as the story ended, thinking about the mastery of what I had just read. Then I read through the poignant afterword, and the whole story made even more sense to me. I strongly recommend that Author's Note, for a personal perspective on what she was feeling as she wrote this, and how she came to see the story when it was complete. I don't want to spoil that here. 
 As an adult reader, I was completely taken away by this book. I would recommend it for most adults, and of course for children above, say, age 6 or 7. There are some frightening bits at various points, but I really see this as one for 'kids of all ages'. 
 Very Highly Recommended
