She Said Yes by Stephanie Nicole Norris

No man enraptured Martha Jean Richards. Not since her scoundrel of a late ex-husband left. Men came with problems, and she didn’t believe in happily ever afters. But even Martha Jean’s hard exterior couldn’t hold after meeting Christopher Lee Rose, a multimillionaire mogul.
He was the father of her recently acquired son-in-law, and Christopher wooed Martha Jean every time he entered a room. Now with a change of heart, Martha Jean decides it’s time she marries a gentleman, but there is one person who stands in her way, Adeline Stevens.
Also, newly joined into the Rose family through marriage, Adeline’s spunky no-nonsense attitude affected everyone she met. For years, Adeline had lived by the rule that men could not be trusted. That was until she met Christopher. Baited by his charismatic charm, Adeline aspires to be the woman at the altar when it’s all said and done. And if it’s war that Martha Jean wants, it’s war she will get.
