She said it's your child 2
(Book)

"Darica's world is turned upside down as she becomes aware that her desires, her husband's selfishness, and her lover's past have created a perfect storm that leaves her knocking on death's door. But realising the error of her ways won't turn back the hands of time and undo the unthinkable things she did to get to this point. Rolanda thought she had raised her sons to value women, unlike their abusive, cheating father. She even married another man to give them a better life. She learns, however, that DNA plays a major role in relationships, and family ties are hard to break. Nolan and Dolan don't know it, but the one woman who holds the key to their hearts is fighting for her life. There are choices to make, secrets to reveal, and enemies waiting in the wings." --,(Source of summary not specified)
