Adela was a fun anti-princess; she wanted to work in the garden, have a life instead of get married, and has this great line "I don't care what I look like. I care about what I do." (page 158) How many times have I chanted "useful, not decorative" to my own children? The setting is a standard medieval royal one, which children seem to really like, and Adela is 17, which makes her even more intriguing as a princess. Hortensia's magic is pretty gruesome, if you think about people living as flowers for decades, but isn't too scary for younger readers. The garden details are also very vivid.
