You’ll never believe the terrible things being said about the perfect president of the PTA.

Attempted murder? Inexplicable accident? Either way, a PTA mom struggled for her life in an elementary school cafeteria, poisoned by a wolfsbane-laced smoothie at the fifth-grade graduation party. Now all eyes are on the accused, the victim, and a woman hired to look deeper.

Ambitious defense attorney and single mother Allison Barton is anxious to escape the shadow of the low-down dog of a marquee partner carrying their renowned Virginia law firm. A win for her high-profile new client will give Allison the career she deserves. And PTA president Kira Grant certainly appears innocent—except for the toxic bloom in her backyard and perhaps a bit of a malicious streak. But no one said the innocent had to be likable—or entirely honest. Besides, with an image as carefully cultivated as her garden, Kira would be insane to risk everything on something as outrageous as the attempted murder of one of her closest friends.

What about those in Kira’s orbit, a sunny suburb of moms behaving badly? What do they really know about Kira? What does Kira know about them? For Allison, the answers are getting darker every day.
