"Seduce Me at Sunrise" - Lisa Kleypas - 2008

British vs. American covers...both good, I think.  On the British cover (purple dress) the costume is period appropriate, but it looks very proper -  readers might be surprised by the contents!  The American cover (red dress) is luscious and easily recognized as a series, they do remind me a lot of the recent Mary Balogh covers, which are published by Random House, not St. Martin's - and were released in 2009 - after the Kleypas's first novel in the Hathaway Family Series was released.  Trends in covers, I guess. 

The second book in the Hathaway family series.
