At the outset, I was reminded of Richard Peck's UNFINISHED PORTRAIT OF JESSICA as Ruby deals with her surging emotions about Dad's departure. However, this book is about so much more than divorce. The issues of well intentioned friends trespassing into territory that is mined with unsorted feelings. I think that makes this book so strong: it mirrors the real world in which our teens live and negotiate. Most do not face just one central problem but a myriad of situations that all seem to confront at the same time.
Back to looking at the lovely waves out there in the Atlantic. I write this from south Florida where I am enjoying a few days off before classes start fast and furious.
ETA: Here is the cover. Thanks, Siobhan!
