I read three books prior with a promising plot just to end with a finale that didn't feel final? Who is the editor for this series? Is there even one??

How does Maz drop a line like "I've loved you for many years" when we never got that acknowledgement through out the past three books? He loved her for a decade?? She was in his dreams?? He's over 100 years old but told Reyna that the curse must be broken before his 30th birthday?

Human years or not, Why was that no explained earlier in the series so that us readers wouldn't be this confused while reading the last book? We knew he had secrets but why was THAT hidden now?
I could of read this for free on Wattpad. That's how horrible book four of this series is. If you just need four extra books to help you complete your reading goal, then pick this one. I finished the four books in two days.
