Tilda Finch is a successful businesswoman, a mother to two wonderful adult daughters, and besides an unexpected divorce, she's living a relatively happy life. Until she wakes up one morning and her finger seems to have disappeared. She thinks back to the kombucha she drank the night before-perhaps it was spiked?
Studying herself in the mirror, she discovers one of her ears has also disappeared! She rushes to the doctor, who after a multitude of tests says she's sorry to inform her that she has invisibility, a disorder that affects millions of women worldwide, mostly after the age of forty-she is disappearing, and there is no cure.
Tilda isn't overly surprised. She's felt invisible for years. But after attending a support group for women like her and seeing how resigned they are to simply fading away, she thinks there must be a better way. Hesitant, she seeks out a controversial therapist who compels her to realize that she can't expect the world to see her if she can't first see herself.
