It Happened One Season/Stephanie Laurens et al/420 pgs.

Stephanie Laurens, Mary Balogh, Jacquie D'Alessandro, and Candice Hern have each written stories containing the following elements: a hero returning from war and reentering society; a heroine who has been unsuccessful in society (close to being "on the shelf"); and the hero's older brother has only sired daughters, so the hero must marry with the hopes of producing a male heir. It's an enjoyable read seeing how each author weaves these elements into a regency romance.
