The overall set up (without spoilers, so it’s a little plain). Katie Greene moves from everything familiar in her life after her mother’s death, to live with her aunt half way around the world in Japan. Things are not easy; she socially faux-pars constantly, struggles writing and reading kanji, misses her mum. Then Tomohiro comes into her life and makes the impossible happen. The ink on the paper first, begins to move and then becomes real... and try to kill Tomo.
It is a great series. A little over the top at times (the love hotel in the first book... come on! What was that supposed to achieve?) and Katie is on the annoying side (she’s one of those heroines who only wants to do good. Though I might dislike her mostly because she gets Tomo) but overall the series was enjoyable and engaging. A killer read (don’t worry the ink in the book won’t kill you). So go back to the beginning with Ink.
