When 14 year old Lisa learns that her sister, Susan, is really her birth mother she runs from the loft she shares with Susan and Susan's NYPD detective husband Dave. When she subsequently vanishes Dave realizes it's eerily similar to the only unsolved case he's ever had, another teenage girl who disappeared a year ago.
The story was good, the plot fresh and while the characters could have been more fully developed, they were basically likeable. Dave was a caring man who was able to forgive Susan for her secrets and Susan was able to forgive herself for the choices she made when she was little more than a child.
The reason I gave it a three was the information about Bipolar Disorder, AKA Manic-Depressive Disorder. Such as: "criminals often had manic depressive tendencies, to say the least." "Rage and repentance, that was the usual cycle." In reality most people with mental illness are more likely to be the victims of crimes, not the perpetrators. The manic state of Bipolar Disorder is more often manifested as excessive excitement, enthusiasm and activity, rather than rage. The "depressive" state is more often characterized by sadness, despair, inactivity and withdrawal, not repentance. People who have mental illnesses, key word "illness", are not "insane", except in cases of a true psychopath. I'm Bipolar so not only do I have my own personal experience, I have done a lot of research. Mental illness is very misunderstood. If Ms. Pepper had done sufficient research she would have made it less so, instead of presenting a false picture.
Still, I would probably read another of her books.
