A Season to Remember — Ava Stone

In Jane Charles's Devil in My Dreams...
Devlin Bartlett was never meant to be Viscount Marston, yet he has inherited not only the title but three younger sisters, all of marriageable ages. He soon learns that thwarting the French was much easier than playing guardian to three young ladies, and decides the simplest solution is to marry them off. * Louisa Whitton needs to find a husband of her own choosing before Christmas. At her sister's house party, she meets the perfect gentleman -- thus foiling her grandfather's plans. However, Marston refuses to even think about courting her until his sisters are wed, and he has the audacity to ask her to wait. Louisa's grandfather will never agree, so she sets out to find the perfect substitute for Marston, forcing him to choose between his sisters' future and his own.

Especially when they treat her as if she's still a little girl in leading strings. 
* Enter Drake Lockwell, Viscount Flitwick. He, too, is typically eager to escape crowded ballrooms and matchmaking mamas in favor of his own company in a deserted garden or library. But a chance meeting in his brother's garden one night changes everything. Miss Bartlett is young and impetuous, yet he can't help but fall prey to her charms. Perhaps she will be the one to finally mend the hole in his heart...

Or will his secrets be more than Penelope is able to handle?
