Iron King, Iron Daughter, & Iron Queen
The series as whole is incredibly unique and detailed with so many fantastical creatures. It really is a different world, scary and new, but one that you want to learn more about.
I am sooooo glad there is a fourth book and it’s in Ash POV because I don’t think I would have been able to wait after reading the ending of Iron Queen. So be on the lookout for my Iron Knight review, COMING SOON!
