Prada and Prejudice by Mandy Hubbard (Published by Penguin Books, June 11, 2009)
To impress the popular girls on a high school trip to London, klutzy Callie buys real Prada heels. But trying them on, she trips...conks her head...and wakes up in the year 1815!
There Callie meets Emily, who takes her in, mistaking her for a long-lost friend. As she spends time with Emily's family, Callie warms to them—particularly to Emily's cousin Alex, a hottie and a duke, if a tad arrogant.
But can Callie save Emily from a dire engagement, and win Alex's heart, before her time in the past is up?
I've read several reviews of this book recently and I'm really looking forward to reading it. The concept sounds really cute and I love history and romance!
