First off, I'd like to mention that the hero's nickname for the heroine was "Copperhead" which probably says everything you need to know about this book. Personally, I laughed and laughed at that.
I liked the characters, setting and tone, but the whole blackmail thing kept throwing me out of the story. I mean, I can understand Antonia's reason for lying at first, but at a certain point it just seemed like TSTL behavior. In fairness, the other characters involved had the same reaction I did, so I'm sure it was deliberate, it just got dragged out too long for me.
Also, there was a certain element of "the gay guy did it" that I wasn't sure how to interpret. I mean, it was important to the plot, but not integral to the character's badness so it could just be the way people talked about homosexuality in the '70s that threw me?
Despite those quibbles, it was fun and I'm looking forward to reading more by Holland.
