She’s your best friend.
She knows all your secrets.
That’s why she’s so dangerous.
A single mother’s life is turned upside down when her best friend vanishes in this chilling debut thriller in the vein of Gone Girl and The Girl on the Train.
It starts with a simple favor—an ordinary kindness mothers do for one another. When her best friend, Emily, asks Stephanie to pick up her son Nicky after school, she happily says yes. Nicky and her son, Miles, are classmates and best friends, and the five-year-olds love being together—just like she and Emily. A widow and stay-at-home mommy blogger living in woodsy suburban Connecticut, Stephanie was lonely until she met Emily, a sophisticated PR executive whose job in Manhattan demands so much of her time.
But Emily doesn’t come back. She doesn’t answer calls or return texts. Stephanie knows something is terribly wrong—Emily would never leave Nicky, no matter what the police say. Terrified, she reaches out to her blog readers for help. She also reaches out to Emily’s husband, the handsome, reticent Sean, offering emotional support. It’s the least she can do for her best friend. Then, she and Sean receive shocking news. Emily is dead. The nightmare of her dis-appearance is over.
Or is it? Because soon, Stephanie will begin to see that nothing—not friendship, love, or even an ordinary favor—is as simple as it seems.

It starts out as a simple friendship between two mommies whose children are best friends. At some point, the mommy blogger Stephanie agrees to A Simple Favor for her friend Emily, taking care of her son while she goes away for one night.
When it turns into a disappearance, Stephanie and Emily’s husband Sean begin helping each other with childcare…and then become close friends. It all morphs into a live-in relationship between them.
Meanwhile, in alternating narratives, we learn more about both Emily and Stephanie, and later we get a closer look at Sean.
Just when we think we have figured it all out, more darkness is revealed. By the end, I didn’t like any of the characters and concluded that they were all nefarious and not to be trusted. And definitely nothing about any of them is simple. 4.5
