Will Grayson and Will Grayson are two teen boys who live near one another, but their names are where their similarities end. Their lives overlap--and continue to overlap, thanks to the fabulously loud and flamboyant Tiny Cooper, one Will's best friend and the other's love interest. It's Tiny who really shines here, and this is one teen book that is less about finding love than it is about finding love in your friends, in yourself, and in the person you choose to be.

Someday is the sequel to the YA novel Every Day, which offers the interesting premise of a person who wakes up in the body someone else each day. "A," as the character calls themselves, has no body of their own and never knows what life they will be living from day to day--but they try to be good stewards of the people they inhabit each day, mostly just trying to get through without causing harm. In Every Day, A fell in love with Rhiannon and grappled with the difficulties of a relationship under such bizarre circumstances.

They also encountered another "traveler" named X, who doesn't have intentions quite so noble and who wants to partner with A. Someday puts X in pursuit of A, with Rhiannon and her friends in the middle, and A and Rhiannon still agonizing over how to manage their love for one another.

While this last piece--the romance--is the weakness of the book (it suffers for the angsty passages that could be in any teen romance), the overall premise was enough to keep me reading.

But what's most interesting about this book is not really the story itself, but the unique way that David Levithan weaves in discussions on identity, gender, acceptance, morality, love, art, and a whole host of other issues relevant to teens. It's not subtle, but the issues are framed in such a way to make the reader ponder them and how they might apply outside of the fantastical world of body-hopping beings.

In this YA novel, “A” wakes up in the body of someone else each day. They never know where, or who, they will be from one day to the next, and just try to get through the days causing no harm to their host.

This means no relationships, no real identity that anyone else knows. But everything changes when they fall in love with Rhiannon. The two grapple with the difficulties of a relationship under such bizarre circumstances. A unique, magical premise that touches on issues of gender and identity.
