* Olga Dies Dreaming, by Xochitl Gonzalez -- A deceptively light-hearted book about a wedding planner and her politician brother that takes on serious themes of love, commitment, and betrayal. Bonus points for its portrayal of political activism in Puerto Rico.
* Free Love, by Tessa Hadley -- Somewhere I've read that every novel is about whether life is worth living. I'm not sure that's true about every novel (Don Quixote? The Phantom Tollbooth?) but this book definitely is. Phyllis Fischer blows up her perfect life, provoking the question of how much damage you can do in pursuit of your true self before it becomes unforgivable.
