Query: Scary first novel

"Jinn" is a scary, intriguing story and a great first novel for Mr. Delaney. I found it a little slow getting started, but after a few chapters it was hard to put down. The only problem I found with the book was the poor editing. There were many typographical errors, incomplete sentences and some loss of story continuity. I don't blame the author for this since overall the story was intact. I look forward to this author's next novel.
