Query: Disappointed

"Circuit of Heaven" was so intellectually exciting and original that I would have taken any book by Dennis Danvers on faith. But I'm finding it very hard to believe that these two books were written by the same person. Maybe if you like Romance novels "Time and Time Again" would have some appeal. To me, it was sappy, predictable, uninteresting and unengaging. I couldn't get halfway through it. Did he really write this book?
