On Wings of Devotion

by Roseanna M White

Published 7 February 2020
All of England thinks Phillip Camden a monster--a man who deliberately caused the deaths of his squadron. But as nurse Arabelle Denler watches the so-dubbed "Black Heart" every day, she sees something far different: a hurting man desperate for mercy. And when their paths twist together and he declares himself her new protector, she realizes she has her own role to play in his healing.

Phillip Camden would have preferred to die that day with his squadron rather than be recruited to the Admiralty's codebreaking division. The threats he receives daily are no great surprise and, in his opinion, well deserved. What comes as a shock is the reborn desire to truly live that Arabelle inspires in him.

But when an old acquaintance shows up and seems set on using him in a plot that has the codebreakers of Room 40 in a frenzy, new affections are put to the test.

A Portrait of Loyalty

by Roseanna M White

Published 8 September 2020
Zivon Marin was one of Russia's top cryptographers until the October Revolution tore apart his world. Forced to flee to England after speaking out against Lenin, Zivon is driven by a growing anger and determined to offer his services to the Brits. But never far from his mind is his brother, whom Zivon fears died in the train crash that separated them.

Lily Blackwell sees the world best through the lens of a camera and possesses unsurpassed skill when it comes to retouching and re-creating photographs. With her father's connections in propaganda, she's recruited to the intelligence division, even though her mother would disapprove if she ever found out.

After Captain Blackwell invites Zivon to dinner one evening, a friendship blooms between him and Lily that soon takes over their hearts. But both have secrets they're unwilling to share, and neither is entirely sure they can trust the other. When Zivon's loyalties are called into question, proving him honest is about more than one couple's future dreams--it becomes a matter of ending the war.
