Mildred is back again, this time with water!
It seems these books run one term per book, their school has two terms per year and this is the fourth book, so she is in the second term of her second year.
The book starts off rather badly for Milly, as they always do, as she is forced to replace her lovely, though hopeless cat, Tabby, with a more professional and elegant cat, Ebony. She is beside herself, but there may be hope. The wizard she helped in the last book, Algernon Rowan-Webb, has invited all of the second year to stay at his coastal castle for a little holiday and Milly has an idea to break Tabby out of his life of mouse catching.
This is definitely the best so far of the series. It's nearly twice as long as the first two, which helps give a more substantial plot, though it's still very short. It is nicely illustrated, more frequently than before perhaps, I like the faces, the expressions shine a light on the story. Being outside the school for the majority of the book also helps bring a bit of life to affairs.
It's a nice little series, if a tad simplistic.
