The is effectively the last book if the series as book X is just an afterthought. I am very glad I made it through the series and would definitely had done it all over again. I have listened to the entire series twice and am thinking of listening to it a third time.
This last book was one of my favorites as it actually brings everything to a close. The action is intense and it leaves you not wanting to pause. I don’t want to ruin the story so I don’t explain everything, but it wraps it all up in the capitol and pretty intense.
Don’t give up now, yo ure almost at the end and you will not regret it.
