Keeping the Castle by Patrice Kindl
Althea is seventeen and trying desperately to keep the family's castle standing and keep up the family's appearances as well. She's also seeking a wealthy husband to ensure future funding.
The very rich Lord Boring seems a perfect choice, but his business partner Mr. Frederick's keeps getting in the way.
A really funny comedy of manners, one of my favorite parts is when Althea has to come up with something to feed visitors, so she sends servants to catch tadpoles in the moat and spreads it on toast.
A little romance, a little historical, but mostly LOL funny!
