★★★★

A charming story about yet-another-weird-boarding-school, a Hogwarts 2.0 with Nonsense vs. Logical instead of Slytherin vs. Gryffindor. Of course, the YA tropes had to be nourished – there is the question of identity, the ever-present “parents want to have back their little girl”, romance vs. sex. But the author built a charming setting that every speculative fiction reader yearns for. Because who wouldn’t like to get his own doorway to flee reality like Alice’s Wonderland or Narnia? Well, me. I wouldn’t.
Nice characters, easy to read narration, a predictable plot, and a rushed ending. A quick read, fine filling of blanks between two novels.
