The Education of Ivy Leavold by Sierra Simone

I knew I was taking a risk loving a man like Julian Markham. But I thought that love was enough to cover over his darkness.
I thought wrong.
Ivy Leavold came to Markham Hall looking for a home and a new start, and instead she found the enigmatic Julian Markham–along with a love that threatened to consume them both. Now Mr. Markham is offering her a new life as his bride, as the mistress of Markham Hall, and Ivy wants nothing more than to say yes.
But Ivy knows that the closer she binds herself to Mr. Markham, the closer she binds herself to danger. And the deeper their love grows, the closer she gets to discovering the truth surrounding her cousin’s death. Once she does, the explosive secret will rip them apart…possibly forever.

This is the second novella in the Markham Hall Trilogy.
