His Steel City Promise (Colorado City Series Book 3) by Emilee Harris

This is the third book in this series, and it is about William who we find is the Dukes' and Lucy's secret baby. This story finds William finding out exactly who he is and how he reacts to the information. I found Will's reaction to the news somewhat childishness for a twenty-six year old. His reactions to Mila Santiago come from knowing the secret of his birth, and he handles the situation with a maturity and grace that cannot be found in most men. This story is as well written as the first two and cradles itself as a well fit into the trilogy.
