Red Sister

3.5 stars in reality. There are moments of excellence, but also some longeurs and a few too many “coincidences” which are blatently present simply to set up the finale. Fortunately these don't detract from the overall story, which is much more action packed and blood-thirsty than you might expect in a book about a school for nuns.

One final point, this is obviously not intended to be a standalone book, with a myriad of unresolved mysteries at the end, so the reader should probably enter this world with an expectation to read the sequel, to avoid frustration.
