Self-made business owner Dale McGuire has always enjoyed two things in life: women and fast cars. Now in her mid-30s, she's restless and can't work out why. Then one day a 10-year-old boy turns up, claiming to be her son, and her simple ordered world turns upside down.

Rebecca Harper bears the emotional scars of her father's crimes, and now she has two rules: never let anyone get too close and never admit weakness. Thanks to an anonymous egg donor, infertility didn't stop her from having her son Jake. Now pregnant for a second time, she's horrified when Jake brings home the woman he believes is his other mother.

When distrust turns to understanding and passion, can Dale and Rebecca, two women bound by fate, make a family neither expected?
