An enchanted train. A forbidden love. And a deadly secret that could derail an entire kingdom.

Princess Delana will do anything to save her kingdom—even marry a stranger. With her realm’s memory magic fading and her grieving father using the last of his powers to relive the past, Delana agrees to a political union with a rival prince. She boards a lavish, enchanted wedding train bound for her new future and surrounded by his court, secrets, and expectations.

She didn’t expect Bastian. Once her childhood friend, now her brooding, fiercely loyal bodyguard, Bastian awakens everything Del must suppress, even as she dances in her fiancé’s arms. But when her handmaiden is murdered on the night of the first ball, Del is revealed to be the true target. Now she and Bastian race to uncover the assassin before the train reaches its final stop.

As danger closes in and forbidden desire ignites, Del must decide: What will she risk for Bastian—and what might it cost the kingdom? Because their passion may be more lethal than the killer.
