Time travel to 1815? Easy. Pretend to be a singing master? Sure. Don’t fall for your student who happens to be an Earl’s daughter? …Oops.

Caleb Grayson has had better weeks.

His secret time machine project? Discovered by federal agents. His brilliant escape plan? Works perfectly—except now he’s stranded in 1815 England with a broken device, no money, and a serious problem: he needs food and a place to hide.

Solution: Convince a wealthy Earl that he’s a highly qualified singing master from the Continent. How hard could it be?

Turns out, not hard at all. The hard part? His new student.

Adelaide Ravenshaw is accomplished, intelligent, and being aggressively marketed for marriage by her desperate father. She’s resigned herself to a strategic alliance with some boring aristocrat—until her new teacher walks in and starts asking dangerous questions like “What do you want?” and “Have you considered that duty is overrated?”

Caleb knows the rules: Fix the machine. Don’t get attached. Definitely don’t fall for the Earl’s daughter who lights up when she sings and makes him forget he’s supposed to be leaving.

Adelaide knows her duty: Marry well. Save the family reputation. Definitely don’t fall for the mysterious teacher who looks at her like she matters more than her accomplishments.

They’re both extremely good at following rules.

Until they’re not.

When Adelaide’s father announces her engagement to a man she doesn’t love, Caleb faces an impossible choice: abandon her to a loveless marriage, or risk everything to give her something no one else has—freedom.

Time travel is complicated. Falling in love is messier. And sometimes getting stranded in the wrong century with the right person is the best accident that ever happened.
