Bellairs John : Dark Secret of Weatherend (Hbk)

When Anthony Monday stumbles upon the diary of J.K. Borkman, he thinks he's unearthed a worthless piece of junk. But Borkman's mysterious writings turn out to be much more--plans to turn the world into an icy wasteland. By the time ghastly weather sets in and Anthony realizes it's Borkman's fanatical son who is bent on carrying out his father's horrific work, it may be too late to stop him.
