The best news is how much of the trilogy's original muscle is still here. What made Ninth House worth the effort was the refusal to make Yale beautiful, and that instinct is intact: the societies are still a rigged system with excellent catering, and the horror is still administrative before it is demonic. The reviewer at 25YL, who came to this one on launch day, called it a strong, unsettling send-off that trusts its weirdest instincts, and I think that is exactly right, including the word weird. Alex is at war from the first page, the allies she spent two books collecting all get a job to do, and the balance of power between her and Darlington, which the whole series has been quietly building, finally pays out in a way that cost me sleep.

The documented reservation comes with the territory of a launch-day read, and the same reviewer made it honestly: this is a finale being measured against everything the trilogy set up rather than against years of rereading, and there is no way to know yet whether the backwards structure will hold up on a second pass. I will add my own version of it: readers who never clicked with Bardugo's Yale are not going to be converted by a third corrupt society, and the ending she has chosen is deliberately ambiguous, which will satisfy some of us and infuriate the rest. She has said she wanted an ending that leaves readers hopeful and shaken at the same time. That is a fair description of what this does.

On audio, nothing has slipped in seven years. Fortgang and Axtell are still the two halves of this story, the production handles the flashback structure so cleanly that I never once lost track of when I was, and Axtell's Darlington remains one of the better pieces of voice work in the genre. If you are three books in, this is the ending you were owed. If you are not, start at Ninth House and take it in order, because Hell Bent is not a book you can skip.
