My Dear Miss Dupré (American Royalty #1)
Grace Hitchcock

Willow is presented with thirty potential suitors from the families of New York society's elite group called the Four Hundred. She has six months to court the group and is expected to eliminate men each month to narrow her beaus until she chooses one to marry, ending the competition with a wedding. Willow reluctantly agrees, knowing she must do what is best for the business. She doesn't expect to find anything other than a proxy . . . until she meets Cullen Dempsey, and she must discover for herself if his motives are pure.
