A fitting end, even if it didn't recapture the high of Book 2. We get as far into Lucifer's head as Carey is ever going to let us, just in time for his most poignant moments. Things end, begin and change in spectacular, bittersweet fashion in an epilogue whose mood recalls other epics like Sandman, His Dark Materials, and Lord of the Rings (and, in one less epic but equally heartwarming scene, the end of Avengers). 

Fellow disciples of Mazikeen will thrill at the close of her story, which cements the fact that she has carved out a way to serve Lucifer without relinquishing her own sovereignty. Honestly, even without the chewy philosophical quandaries, this run is worth it for Mazikeen and Elaine. If they taught Elaine's story in Sunday schools, the world might be a kinder place.
