The duke knows best
(Book)

"Lord Randolph Gresham has an up and coming career in the Church, and has come to London for the season to find a wife. A feisty and dangerously attractive young woman who insists she'd never marry a clergyman keeps distracting him. This shouldn't be a problem--they'll just avoid each other. When they're forced to sing together, though, the duet is a deeply sensual experience. Verity Sinclair, daughter of the Dean of Chester Cathedral, hasn't changed her mind about the future. But Randolph proves hard to resist, and when they finally give in to their passion, there's only one option left: marriage."--Goodreads.
