This is a very well-written story with complexity and depth of characters. The relationships between all the characters are well-developed. This is not strictly a romance in that it involves warfare, struggles between social classes, unconventional lifestyles, espionage and intrigue. The prologue examines an all-boys school where a few of the older students, all aristocratic sons, molest some of the younger boys. This is where the main character, Valentine Aston, the illegitimate son of Charles Faringdon, the Earl of Faringdon, comes to the rescue of a younger boy who has been abused by Lord Stanton. While it is a disturbing topic the author deals with it in a forthright manner rather than using graphic or inappropriate language. Val gives Stanton a severe beating and is sent down from school because of it. Rather than turning to his father, he enlists with the army and is sent off at the age of 16. Val keeps in touch with his younger half-brother through letters over the years and sees him only on a few occasions. The total acceptance by Charlie of his older half-brother causes them to forge a close bond. Later, they are reunited in Portugal as Charlie is now also in the military. They spend time together and draw even closer. At one point before a battle Charlie gives Val his ring, the crest of Faringdon, for safekeeping. Charles makes Val promise to return the ring to their father personally if anything should happen to him. Unfortunately Val must keep that promise. In the meantime Val's friendship with Elspeth Gordon, daughter of Major Ian Gordon, continues developing. After Charlie's death, it becomes more, and he offers marriage due to the circumstances. While they both love each other it is not declared openly and their marriage begins with a sense of companionship and close friendship. As the story unfolds, we see the tough decisions that Val must make between friendship, especially as it pertains to the Marquess of Wimborne, James Lambert, who treated Val as an equal during their school days, and duty to country when a traitor is discovered. There are interesting and humorous secondary characters that add to the plot like Mags Chase and Will Tallman as well as Juan Sanchez and Jack Belden. This cannot be classified as a clean romance as it does contain scenes of intimacy but, again, the author does not graphically describe anything in a titillating fashion so neither is it erotica. She handles things in a realistic manner and doesn't dwell too long on the few scenes described. Overall, this is a well-told, complex story with real heft to the characters and plot. It is not a fluffy romance with stereotypical characters where everything is wrapped up neatly by novel's end. Having said that, this is a very satisfying read where things do work out in the end but not as you may expect. This is a solid 4-1/2 stars.
