I loved this sequel and the transition to multiple POVs! I enjoyed One Dark Window, but the deeper world-building, evolved magic system, and the shift to Elm and Ione as our primary romance made this follow-up a stand-out for me. I particularly enjoy when an author can pull off a tight story arc in a duology, and this nailed it - the ending felt appropriately hard-won and resisted easy heroics. I adore the Nightmare, and the complexity in his characterization, and I appreciated the sharp humor he brings to character interactions. This is a dark and atmospheric story with two affirming and compelling romance arcs, and I highly recommend to fantasy romance lovers!
