Sukie has a serious problem with narcissism. When she can't see her reflection, she will use her phone's camera to take a "selfie" (a picture of herself) just to make sure she looks OK. Her mother's present of an antique full-length mirror is thus very welcome. But weird things start to happen: at a tennis match, a strange man man attacks her father, her mother disappears to a "spa" and returns with a nose job, and the mirror itself mysteriously develops holes and cracks. Only the family dog Senor seems to know what is going on.
Erroneously billed as YA, there really isn't much in this story (aside from the age of the heroine) that is teen. Instead, this is one of those bizarre "modern novels" of which I am such a fan (not!). The mirror is probably symbolic, but I didn't get it. The characters are numerous and largely forgettable, and thus hard to track. And, in the end, I couldn't figure out what the point was. Read at your own risk.
