Love, tv-shows, christmas, magic phone and Harry Potter refrences... So many good things.
In the magical month of december, Georgie tries to save her marriage and sort out her life. And she just happends to find out, that her landline calls to the past.

This made me believe in love, as do all of Rainbow Rowell's books. The characters are realistic, and sometimes a bit annoying as people are in real life.
