Query: winter of the wolf moon

Having just finished A Cold Day In Paradise, I was anxious to see if Hamilton could equal the quality of his first effort. Happily, his second book is even better! His ability to evoke the stark atmosphere uf the UP and the power of his narration have both improved and intensified to a marked degree. If he keeps this up, he will become one of our premiere writers of mystery fiction.
