This book was totally worth reading, I guaranteed that you will be maze by it. If you wondering should you read Beastly first or not then you don't have to worry about it too much, Beastly not a sequence so it's still fine if u hadn't read Beastly. Bewitching is another story and really interesting too so don't think too much and read it NOW.
P/s: I also recommend Beastly too.
