Unbecoming by Jenny Downham

Katie is seventeen and in love with someone whose identity she’s afraid to reveal.
Unbecoming
Caroline, Katie’s mother, is uptight, worn out, and about to find the past catching up with her.

Mary, Katie’s grandmother, suffers from Alzheimer’s and suddenly appears after years of mysterious absence.

As Katie cares for an elderly woman who brings daily chaos to her life, she finds herself drawn to the grandmother she never knew she had. Rules get broken as allegiances shift. Is Mary contagious? Is “badness” genetic?

In confronting the past, Katie is forced to seize the present. As Mary slowly unravels and family secrets are revealed, Katie learns to live and finally dares to love. 
Unbecoming
is a vivid and exhilarating celebration of life and learning to honor your own story.
