A thoroughly satisfying conclusion to a most imaginative trilogy. If nothing else, Bertie has taught us to remain steadfast in our beliefs and that one must never underestimate the power of words. 
 A great element of this series is the humor and the 4 faeries do not disappoint. They have so many funny quotes and really, I do wish I have the four of them as my best friends. Action-packed this book most certainly is, it's very fast paced and surprisingly, I loved every moment of it; not a single scene I disliked. 
 I loved how everything came full circle at the end of the trilogy and how Bertie fully discovers her powers and what she truly is capable of. The ending is a, I feel, happy ending, but mostly because I knew it was going to happen this way. (view spoiler)[As much as people like to think it's a love triangle between Nate, Bertie and Ariel, I didn't agree because while Bertie loved the guys somewhat equally, Ariel's heart was always for his freedom and I don't think Bertie would have been able to live with that. Although, I did tear up at the part when Ariel talked about Bertie's unwanted child having silver hair. (hide spoiler)] 
 Overall, a most amazing trilogy and I look forward to reading more of Lisa Mantchev's work! :)
