The Way Things Should Be by Carrie Carr

With long-standing family issues settled in the previous novel, Strength of the Heart, Lex and Amanda thought their biggest problems were behind them. But they were wrong. Trouble brews when two family members - one known, one unknown - come into contact with Lex and Amanda, and suspicious things start to happen. Someone wants to force Lex to give up land she recently purchased. An explosion is set off by unknown people down by the creek. Somehow, finances thought safe have been tampered with. Meanwhile, Amanda's sister Jeannie prepares for the birth of her first child, while Amanda feels her own biological clock ticking.
