A Scot Mess

Laird Oliphant's sons have no choice but to get married. Without an heir, the laird has gathered his sons--his six illegitimate sons, all born in the same year--and declared whoever presents him with a grandson first, will become the next Highland Laird.
Reactions are...mixed.
But to Finn Oliphant, this is exactly the news he's been hoping for. You see, Finn has already chosen his future wife: the vivacious and intelligent Fiona MacIan, whom he fell in love with the previous year. He knows she's in love with him as well, so this whole "marriage ultimatum" thing should be easy-peasy. He'll simply invite Fiona to Oliphant Castle to sign all the betrothal contracts and... Bam! Done! They can get on with the baby-making!
Except...
It's not that Fiona is getting cold feet, exactly. She's fairly certain she loves Finn. Mostly. Well, verra likely, at least. But she's never been the most self-confident woman, especially compared to her sister--her identical twin sister--whom Finn happens to mistake for Fiona upon their arrival at his keep, which is super-awkward all around.
The idea of marrying Finn makes her feel all warm and giddy--hopefully that's just lust, not the ague--but how can she be certain he truly wants her, and not just any woman?
It's hard enough to be certain of anything on Oliphant land, especially with Finn's mad Aunt Agatha spreading rumors, five potential brothers-in-law offering terrible advice, and a mysterious ghostly drummer keeping the entire keep awake at all hours.
And mayhap Finn should've mentioned his identical twin brother as well? That information likely would have saved everyone a lot of headache...and a lot of heartbreak.
Finn and Fiona have plenty to learn about themselves, and one another, before they can be certain this marriage is a good idea. But unfortunately, they're running out of time. Dun-dun-duuuuuuuun!
Warning... This comedy of errors is not for anyone who can't handle the following: plenty of naughty scenes, more than a few anachronistic jokes, and an embarrassing number of mistaken-identity gags. Only pick up this book if you have a sense of humor. You've been warned.
