The last thing retired teacher Nancy Brewer wants is to be answerable to someone else for her every move, every decision, every problem she could sort out herself, just because she has recently been widowed and her daughter worries. She isn't ready to be treated as a vulnerable old lady. What she wants is to fulfil some of the retirement dreams she and James had shared.

The catalyst for change is an unexpected visit from her beloved grandson, whose infant difficulty with pronouncing her name created Nana Boo. When she receives sinister phone calls and an arsonist strikes, layers of truth, secrets and lies in her loving family are peeled away. They are all faced with how they have deceived each other, often with the best of motives, choosing between love and honesty.

Will Nana Boo finally be able to decide how far to let her family determine her future?
