Ruby Red II - Il segreto di Zaffiro

If you have seen the first one (or read the books, haven't done the latter myself), you are already hooked. Still there is a "review" of sorts, with our main female protagonist "remembering" what happened up to the point we catch up to her. Obviously relationships have evolved and things go to the next level (also literally). The physics of time travel are sketchy and there are many secrets (especially for those who haven't read the book I reckon), but this is aimed at a younger audience and the viewer should know that.

It's made clear after all from the beginning (in case you hadn't seen the first one "Rubinrot"). There are things that teenage girls have to deal with and those issues collide with the whole "saving the world or whatever" plot that is going on. You might not be intrigued by all that, but the audience this is aimed at, should be delighted.
