... this author spirits you away into a realm of impossibilities made possible, a time-warped world where magic still resides in the midst of New York City. Mark Helprin weaves literary sorcery like no other author, and his lyrical touch makes every sentence a treasure. A huge, thick, cant-put-it-down read where you can't ever fathom what's next, because all the normal rules are suspended here. The backdrop of Snow-Queen reminiscent winters only increases the magic of this tale. No other style of writing is quite like Helpern's, whose voice is unique and opens the reader's mind when least expected.
