What You Remember I Did — Janet Berliner

What You Remember I Did is a Baby Boomer love story, full of the complications of adult life. Struggles such as estranged children, an ailing mother, an ex-husband, grandkids, and the kinds of deep secrets that life brings. For Nan Jenssen and Matthew Mullen, it's a recipe for passion and conflict.
Nan is a middle-aged tennis coach at an upstate New York community college and spends her evenings watching old movies with her mother, who is slowly slipping into dementia. Then a co-worker sets Nan up on a date with Matt, the incoming poet-in-residence. He's handsome in a James Mason way and very intelligent, but Nan senses something beneath that surface. Of course, she's been sensing that with every man since her husband of more than twenty years confessed that he was gay and left her.
In Matt's case, the secret he's hiding is that he has an estranged son who has accused him of abuse based on "recovered" memories. Since Matt won't talk about it, Nan finds the son's therapist and poses as a new patient to find out if the woman is brainwashing her patients, or if Matt really is abusive. What follows spins Nan's world out of control, and puts her own ailing mother's life in danger. All because the therapist has a secret so dark, she keeps it even from herself.
