This book was amazing and i love it. it was helpful to see the dragon world through the eyes of humans. there is a fair chance that this was one of best written books in the wings of fire series. if anyone thinks that wren should have accepted her parent's apology, think again. they tried to sacrifice her to the dragons when she was only 7. also, i am 100% sure sky is kestral's other child and peril's brother since he fits the description of him and a dragon who looks like kestral tried to findhim at the beginning. i hope that in some point in time weather it be in book 14 or 15 or in another legends, we find out what happens to wren and sky with the invincible lord after them.
