Darkest Death (Darkest #2)
Leona Bushman

Lord Archer had loved Sarah all her life, but once her parents died, he'd taken a step back, searching for a wife amongst the ton as a proper lord should, leaving her to heal. Instead, he found himself drawn more and more to Sarah as she matured into the perfect woman to be by his side. However, could she handle the secret life he led? Did she know about her father's secret life? But none of that mattered once she started receiving those damn letters. Someone was out to hurt the woman he loved, and he planned to catch them or die trying. Could he also woo her and remind her of the love and trust of their childhood? Or would the situation keep them apart, or worse, kill the woman he wanted to marry?
