After being blown away with Annihilation and being prodded along with Authority, this was a pleasant conclusion to the strange, disturbing, thought producing world of Area X. I'll be honest that it took me a couple of false starts to get through this book as the first half was confusing, but after we learn about the Biologist's fate the pace picks up and everything that follows has all the same intriguing allure of Annihilation. That everything is wrapped up enough to be satisfying while not really providing a conclusive finale is admirable. 
 Jeff Vandermeer's world building abilities and tone setting are fantastic. When I read something that lingers in my head days after reading it, I know I've read something worthwhile. The fact that almost his entire primary cast are POC is refreshing. While I didn't feel I understood some of the motivations of the characters, especially Lowry, they all felt very developed. 
 After this series, I know I'll never look at St Marks the same again.
