Tilda is Visible by Jane Tara

Tilda Finch lives outside of Sydney and knows she has a good life. Divorced with twin adult daughters, Tilda is stunned to discover one of her fingers is invisible. By the time she sees a doctor, other body parts have disappeared. Tilda's doctor runs some tests and says she has "invisibility disorder." While dealing with the diagnosis, Tilda meets blind surfer, Patrick--but can she even start a relationship with all that she's going through? Tilda decides to do all she can--therapy, mediation, a support group, examining her childhood and marriage--to make herself whole again.
