In the town of Leamington, Ontario, a seventeen-year-old boy is suddenly stricken by a schizophrenic episode and wakes up in hospital. The boy's name is Calvin, and he is plagued by hallucinations.

As the hallucinations persist, Calvin comes to believe that the answer lies in performing one grand and incredible gesture.

And so he decides to walk across Lake Erie. In January. The temperatures have been below freezing for weeks. The ice should hold...

The lake, it turns out, is more marvelous, and more treacherous, than Calvin had ever imagined — populated by abandoned cars (joy ride!), ice-fishing eccentrics, psychokiller snow beings, and a not-so-mythical sea witch named Jenny Greenteeth.

Not to mention the man-eating tiger that looms just out of his sight lines as he treks.

But the biggest surprise of all is that Calvin finds himself accompanied by Susie, the girl of his dreams. Or is it his dreams that have conjured up Susie?

Part romance, part adventure story, part quest novel, Martine Leavitt brings her inimitable gentle wit, humor and compassion to a story about a teenaged boy struggling to gain control of his own mind and destiny.
