Hell Bent by Leigh Bardugo (2023) Flatiron Books

Galaxy Stern returns in a story about the Lethe house at Yale.  This time she is going to try to get her mentor back from hell where he was trapped by his traitorous professor in charge of the house.  But she can’t do it by herself.  Her new Praetor and her sponsor don’t want her to mess with any more arcane attempts.  They want to count her Virgil as simply lost.  But Alex doesn’t know how to give up.

Ms. Bardugo weaves a tight tale of self-recrimination and magnificent effort that keeps the reader guessing all through the story.
