Honestly, I'm confused with how I feel about the ending to this trilogy. On one hand, I'm in love with this series and I think it's such a great romantic love story but on the other, I really do have some doubts on the ending. 
 Abbey and Caspian pretty much get what they want, which is great, but there's definitely questions to that. Without spoiling too much, how do "the people involved" explain things to "the parents involved"? That in itself is the biggest question/problem I have with the ending. (view spoiler)[In addition, while I think it's great that they ended up together, and that Abbey was the one who was meant to die in the first place, the message that the ending seems to be giving is that it's okay to die for a boy you love, and I don't think that's a positive message you want to be spreading to young teenage girls. (hide spoiler)] 
 Another minor "problem" was all the information dump we got, especially regarding the Revenants. I'm sorry, but after reading Die for Me, I can't think of that word without thinking of the book and I have to say, Die for Me did it better. Honestly, I didn't care much for the Revenants in The Hidden. 
 But one thing I WILL give credit to are all the romantic scenes between Abbey/Caspian. I think it's obvious to fans of the trilogy that they've been waiting for Caspian's death day for some time now and lemme tell you, the action that happens on that day, A-M-A-Z-I-N-G!! 
 So, all in all, I'm still confused but it was a somewhat satisfying ending so I don't regret following this trilogy. :)
