Raffa wants to be an apothecary and get out from under the watchful eye of his overprotective father. After all, he fixed Echo the bat all by himself, didn't he? But when a red vine doesn't work the way he expects, he travels to the Commons to warn his cousin and uncle. There, he starts to learn about exactly how powerful plants can be, and whether he wants to use that power for good or abuse it.

I think I would have enjoyed this one more if I hadn't listened to it on audio. I have such a short commute most of the time that it was hard to get into the story.
