Sabrina Jeffries' "Never Seduce a Scoundrel" - #1 in the "School for Heiresses" series

Never Seduce a Scoundrel - Sabrina Jeffries

OK read, but the plot seemed too busy (maybe setting up things for other books in the series) and the way the mystery of Dolly was resolved didn't work for me, especially the scene with the "obedient bride" which was somewhat cringe-inducing.
