Duchess Material by Emily Sullivan

When her student goes missing, an independent bluestocking must seek the help of the arrogant duke who spurned her in this sizzling tale of romance that has "sparkling banter, gentle mystery, and plenty of swoonworthy moments"—for fans of Netflix's Bridgerton series (Publishers Weekly).

Phoebe Atkinson is what society might call unconventional. Instead of marrying well like other women born to wealth, she chose to be a schoolteacher. Not to mention she lives in a leaky flat in an unfashionable part of town rather than stay in her parents’ mansion. But when her most promising pupil goes missing she has only one option: beg her sister’s best friend, the powerful Duke of Ellis, for help. 

The last thing William Margrave ever expected was to inherit a dukedom. But now that he has it, he’s determined to act the part perfectly—and that includes marrying the perfect duchess. A bluestocking Bohemian schoolteacher is decidedly not duchess material. But he can’t resist her plea for help regarding her missing student. 

As they fall further into the mystery, William discovers that he never got over his childhood crush on Phoebe, and he doesn’t really want to.
