The Extraordinary Secrets of April, May, & June, by Robin Benway

In this mixture of YA angst and supernatural powers, April, May, and June are three sisters (named after the months in which they were born - exactly 13 months apart) who are struggling with a new school after their forced move after their parents divorce. What makes them unusual are the powers that they have acquired (April can see the future, May can make herself invisible, and June can read other peoples' thoughts). At first these powers are simply useful tools for coping with school, but when April forsees a tragedy coming, the girls must band together to prevent it. Can they bond as sisters or will their jealousies and distrust doom them?

Of the two components, this book is much bigger on the YA angst (boy trouble, sister trouble, BF trouble, etc.) than it is about the supernatural. There are hints that the powers may be hereditary and there is some discussion about trying to tame the powers, but for the most part this book is really about boys and about sibling bonding. It would even be a bit fair to say that the entire supernatural powers thing probably could have been removed altogether and the story would still hang together. That doesn't mean that it's bad, but that it was unnecessary to add the magic. Perhaps, Benway left it undeveloped so there would be room for a sequel?

In any case, I'm always far more interested in human interaction than magic and I think that the relationship that these girls have is more interesting that the rest of their talents.
