<div>It all begins with a strange coin on a sun-warmed sidewalk.<br>&nbsp;&nbsp;&nbsp;&nbsp; Jane finds the coin, and because she and her siblings are having the worst, most dreadfully boring summer ever, she idly wishes something exciting would happen.<br>&nbsp;&nbsp;&nbsp;&nbsp; And something <i>does: </i>Her wish is granted.<br>&nbsp;&nbsp;&nbsp;&nbsp; Or not quite. Only half of her wish comes true.<br>&nbsp;&nbsp;&nbsp;&nbsp; It turns out the coin grants wishes—but only by half, so that you must wish for<i>twice </i>as much as you want.<br>&nbsp;&nbsp;&nbsp;&nbsp; Wishing for two times some things is a cinch, but other doubled wishes only cause twice as much trouble. What is half of twice a talking cat? Or to be half-again twice not-here? And how do you double your most heartfelt wish, the one you care about so much it has to be perfect?</div>
