This seems like a book one could read in one sitting, on one of those long days devoted to reading. As it is, we stayed up much later than intended to finish it. I found the painful parts manageable and the fun parts only a little on the giddy side -- suitable to the teen POV, at least how we remember those years being more intense than these much later decades. We accompany Mauve/Maeve to her first furcon, a lively gathering (convention) where fans and artists gather and enjoy shared hobbies and interests. (If you've ever dressed up for a renaissance fair, you might relate.)
I'm not a teenager, nor a furry, but you don't have to be either to enjoy this story. Even if you aren't familiar with words like "fandom" or "con" or "fursona," if you've had favorite pop stars, TV shows, cover artists, you'll probably pick up the general lay of the land quickly enough. Definitely recommended, both for pleasure reading on its own merits, and for parents, grandparents, etc.
