Maria Edgeworth 
The Absentee 
Regency Romance Classic

Just before coming of age, Lord Colambre, the young hero of the novel, finds that his mother Lady Clonbrony’s attempts to buy her way into the high society of London are only ridiculed, while his father, Lord Clonbrony, is in serious debt as a result of his wife’s lifestyle. His mother wishes him to marry an heiress, Miss Broadhurst, who is a friend of Grace Nugent. However, Colambre has already fallen in love with his cousin, Grace Nugent, who lives with the family as a companion to Lady Clonbrony. Worried that his mother will pressure him into a marriage with someone he does not love, Colambre decides to leave the London social scene and visit his ancestral home in County Wicklow in Ireland.
The author expresses the systemic evils of the absentee landlord class of Anglo-Irish and the desperate condition of the Irish peasantry. There are many turns of plot and much information about Ireland and details of shallow London fashionable life, and the egregious results of the propertied classes treating their Irish lands as a resource to be exploited rather than as a relationship among classes and with the land.
