Suddenly Royal by Nichole Chase
I mean, that's pretty much the book in a nutshell. Meet Sam -- she's a grad school student studying raptors (ie. birds) when she finds out from a smokin' hot prince and his aunt that she's really a duchess in a country with the weird name of "Lilaria". Romance blooms between the aforementioned smokin' hot prince and the new found duchess.
And...that's pretty much it. Not much danger of spoiling the plot because there really isn't much of one. That's not necessarily a bad thing, though, if you're looking for a fun, quick contemporary romance read.
All in all, I liked it. I just don't know if it has enough momentum to carry me on to book number two when that comes out...
