This book seems to be more back story which is cool but not sure how necessarily it is? Maybe for the Renegades/Archenemies continuation of the series? I’m not sure. I listened to this on audiobook and it was a pretty fast listen.
I can’t say it’s my absolute favorite in the series but I can see what it adds I suppose.
I give this a 3.5/5 stars
