Celeste Prescott discovers her guardians have left her penniless and she must now seek employment. Celeste travels to London and accepts the position of companion to a young lady.  Roderic, The Earl of Campion is a wealthy Englishman and friend to the German prince.  Fate throws Celeste and Roderic into a situation where they are both striving to keep the love struck young lady and the love struck prince apart.  But Celeste and Roderic find themselves in an overwhelming mutual attraction.

An Improper Alliance is an interesting view into the regency life.  Jane Toombs illustrated the standards of society.  I liked Celeste, who is a lady of common sense and doesn’t allow the dictates of society to rule her.  An Improper Alliance is a good story to relax with, I found it enjoyable.
