"Through The Looking Glass" is, perhaps, not QUITE as good as "Alice's Adventures In Wonderland", but it's close enough to still rate five stars. Not, properly, a sequel to the first book, there is no indication at any point in it that the Alice (clearly the same individual, slightly older) from this book ever had the adventures in the first one; there is no reference to her previous adventures, even when she once again meets Tweedledum and Tweedledee. Obviously, the two books are intended as parallel adventures, not subsequent ones.
The most memorable bits from this book are doubtlessly the poem, "Jabberwocky", as well as chapter six, "Humpty Dumpty". But all of the book is marvellous, and not to be missed by anyone who enjoys a magical romp through silliness and playful use of the English language.
