Cursor's Fury (and Codex Alera in general) is a reminder that Jim Butcher can write well. Plot and dialogue are tight and sharp, and character development for most of the main characters is on point. Tavi and his crew (Max, Kitai, et al.) are even more engaging than before, and Lady Aquitaine is as delightfully conniving as ever. Amara comes into her own, proving that good isn't necessarily dumb when she outsmarts the Lady. 
 On the flipside, Isana, already the weakest of the POV characters, alternates between frustrating and boring here. She lost me with her hyper-sentimentality in the face of war, choosing to withhold her healing talents from thousands in need so she can save one man (who she was already unknowingly in love with). The choice to prioritize the life of a man who has been loyal to her for 20 years over isn't wrong - that's enough justification there. But Fade/Araris hasn't been shown to be that important to her up to that point. Set the scenario in a city under attack with thousands dying by the day (with only one overworked healer doing all she can) and Isana appears overly stubborn and selfish as a result. 
 I'll probably skip her parts when I re-read this. 
 Still, Cursor's Fury is great stuff. It restored my faith that Jim Butcher can write great things in the future, even if his most recent work (the awkward and amateurish Aeronaut's Windlass) is a huge step backwards.
