The Heir Affair (Royal We #2) by Heather Cocks

After a scandalous secret turns their fairy-tale wedding into a nightmare, Rebecca "Bex" Porter and her husband Prince Nicholas are in self-imposed exile. The public is angry. The Queen is even angrier. And the press is salivating. Cutting themselves off from friends and family, and escaping the world's judgmental eyes, feels like the best way to protect their fragile, all-consuming romance. But when a crisis forces the new Duke and Duchess back to London, the Band-Aid they'd placed over their problems starts to peel at the edges. Now, as old family secrets and new ones threaten to derail her new royal life, Bex has to face the emotional wreckage she and Nick left behind: with the Queen, with the world, and with Nick's brother Freddie, whose sins may not be so easily forgotten -- nor forgiven.
