I won't talk too much about this book since it's the conclusion to a series. Just know that it was just as amazing as the first. Fisher is an incredible writer and I shall continue to read her books as long as she continues to write them.
The ending to this is a bit open-ended and can continue if she so chooses, which I hope she does since the ending was also bittersweet. If you like fantasy and adventure, then I highly recommend you read this series. It's great~
