Query: Implausible, agonizing read

This book starts out with an implausible premise and only gets more ridiculous as it goes on. The whole "communicating by letter" routine gets old very quickly. Christine Holden is a psuedonym for two authors writing as one. In this case, two heads are NOT better than one. Pass this one by, even if you're a die-hard Regency fan.
