Rachel Whitman has everything. She’s young, attractive, and affluent. Her husband is the brilliant CEO of his own company. They have a big new house in a flossy Boston suburb. They have all the brand-name “toys” that go along with wealth. And they have a gorgeous, sweet little six-year-old son named Dylan.

But Dylan has learning disabilities. Although intelligence isn’t everything, Rachel lives in a community where the rewards for brainpower are conspicuous. She fears her son will grow up never fully appreciating the wonders of life. Like so many middle-class parents who would do anything to improve life for their children—whether it means fixing hair, teeth, or nose—Rachel cannot accept that her child is less than perfect.

Tortured by the idea that something she did in the past caused Dylan’s problems, Rachel becomes obsessed with a secret and expensive medical procedure that claims to turn slow children into geniuses.

Should she and her husband sacrifice their new fortune on the risky, experimental procedure for the sake of their son’s happiness? Unaware of the real consequences of the brain enhancement procedure, Rachel can’t know that the costs of the operation go far beyond financial ones.
