Publisher's Synopsis
Jane finds the coin, and becasue she and her sblings are having the worst, most dreadfully boring summer ever, she idly wishes something exciting would happen.
And something does: Her wish is granted.
Or not quite. Only half of her wish comes true.
It turns out the coin grants wishes-but only by half, so that you must wish for twice as much as you want.
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?
