The Language of Flowers by Vanessa Diffenbaugh

At eighteen, Victoria finally ages out of the system - eighteen years of failed foster experiences, an almost adoption and a life changing mistake.  Through it all has been a primal connection with plants and flowers.  She has even received instruction in the Victorian understanding that each flower carries with it an emotion as well as the exact moment that a grape is ready to become wine.  Which is stronger - the hurt and anger that has become an essential part of her being or the possibility that she can learn a new more hopeful language?  Nothing heavy duty here.  Some of the characters are unbelievably good and the alternating back story/present structure makes start and stop reading tricky but the idea of the language of flowers is most interesting.
