Spoilers ahead.
I anxiously anticipated this book after reading the series starter. Personally I don't consume paranormal content that includes, magic, vampires and warewolves, but I do read alien content. In the first book the Creatus were revealed to be aliens. Fast forward all the way to Book five and it becomes a full on vampire novel, blood consumption and all. I was personally disappointed by this, after the series starter rubbished typical vampire lore, only for Book five to go there anyway, all via another route. To be fair, the preview states that legends of heroes and monsters originated with the Creatus, but that did not temper my disappointment.
Other comments. The grammar was good, I spotted no mistakes on that front. The plot basically got me up to speed with the main events of the three books in between that I skipped (all due to my own impatience). The good thing about that is now I actually want to return to the previous books and read Jonas' story.
Critisims. The main villain came across as cheesy instead as menacing. I didn't get a serious sense of horror from the women held captive for egg harvesting or the room full of incubators where the new breed was being cooked up. The writing didn't convey the inhumanity of those two pivotal revelations.
