Query: Disappointed.

I love Linda Howard when she's good and I usually like time travel romance. This book left me cold. The hero, a police detective, was dull, --meticulous and somewhat clinical. The heroine was an FBI agent from the future who repressed her feelings. The fireworks didn't fly between them. At one point, she punches him and really whacks his chin, which didn't seem any more attractive than when a man punches a woman. The hero is amused by her misunderstandings of today's idioms, but these weren't very clever for the most part. I liked some of the technology, but it wasn't that amazing. The heroine's fascination with cotton clothing was kind of a yawner. I look forward to a better book from this author next time out.
