X, Magnolia, and Miles (X’s dog) were off in a boat trying to find the fabled Metal Islands. Much like previous books, this one had multiple POVs and multiple groups of characters doing different things, but it’s a format that works because there’s always a lot going on, and all of it is important. *The next three paragraphs of this review may contain SPOILERS for previous books in the series.* The scenes that took place on the surface and at sea were full of danger and action and monstrous creatures.

The relationships between characters were also imperfect and complex. The Hell Divers especially deserve some recognition, not just for the way they risked their lives going to the surface but for the way they constantly risked their lives for each other, never willing to leave someone behind if they could help it. The characters were complex and flawed and gruff and realistic but still likeable for their good qualities and their good intentions. The world was complex and horrifying, yet believable. This was another great book in the series with the same great things as the others. These books are so intense, every single one of them! It doesn’t matter if the characters are in the air, on land, or at sea-the author still writes a gripping, nail-biting story.
