"Before She was Helen" by Caroline B. Cooney. If you go to the library, you will be given a copy of this book to keep - while supplies last.

When Clemmie goes next door to check on her difficult and unlikeable neighbor Dom, he isn't there. But something else is. Something stunning, beautiful and inexplicable. Clemmie photographs the wondrous object on her cell phone and makes the irrevocable error of forwarding it. As the picture swirls over the internet, Clemmie tries desperately to keep a grip on her own personal network of secrets. Can fifty years of careful hiding under names not her own be ruined by one careless picture?

And although what Clemmie finds is a work of art, what the police find is a body. . . and she was the last person at the crime scene, where she left her fingerprints. Suddenly thrown into the heart of a twisted investigation, Clemmie finds herself the uncomfortable subject of intense scrutiny. And the bland, quiet life Clemmie has built for herself in her sleepy South Carolina retirement community comes crashing down as her dark past surges into the present.
