Book number 4 and I gotta say, I've really been enjoying this series so far! I hear number 5 is the final? If so there's going to be a lot to wrap up.
We follow Caden (a character I wasn't too keen on in the first book but has since grown on me) as he tries to unravel a mystery about a galaxy consuming entity, it's nature and where it's from.
Without spoiling anything I really, really digged the concepts of this and the reveal at the end of the final battle/third act of this book was spectacularly breath taking, both for the characters experiencing it and us reading it.
I like this authors approach to writing, his stuff is generally very well thought out and researched, the battles, especially the space battles are fun and the pacing, I've noticed that the pacing seems to improve with every subsequent release, which is good. It tells me that this author isn't stagnant and pushes himself, the quality of his work and the scope grows with every new addition.
Am looking forward to book 5!
