So why did Nate feel as if he was at the center of an out-of-control storm? Sarah. Here on his doorstep. The last person he'd ever expected to see was his ex-wife β with a child, no less. And then to hear her say those four incredible words, "Will you marry me?"
But Sarah has to have a life-threatening operation and there's no one to care for little Matty but her. And that's why Nate grudgingly agrees to go along with her plan. Against his better judgment.
