This book started out with sharp humor and a thrill, and got better and better as it went. Ann, the main character, was witty, funny, realistic and vulnerable, and the other characters of Bea, Roger, Father Stevens, Kevin, etc, were well-drawn, likeable and intriguing. Throughout the book, the suspense rose, the humor continued, fascinating bits of history were brought in, and an intriguing conflict between the various characters' Christianity and atheism was introduced and well tied in with the conflict between Christianity and ancient religions in the house. A storm lead to an exciting climax. Then...thud. The ending was a complete let down; it was as if the author got tired of the story or ran into a deadline and just plunked it down. I enjoyed the rest of the book so much that the ending was quite a disappointment and I almost felt cheated. I look forward to reading other books by this author, and I hope in those the endings match the quality of the stories.
