Longer review to come...
In short, a superior follow up to the first book, and I really enjoyed Daughter of Smoke & Bone. In this installment, the romance takes a backseat to the overarching themes of vengeance, compassion and love (romantic and otherwise). What I liked about book one is stronger here, the unabashed shades of gray morality as expressed by the war between the monstrous chimaera and the angels; neither side is right, and both, driven by millennia-old grievances, are more than happy to commit unspeakable atrocities in the interest of satiating their need for vengeance.
Those who thought that Daughter of Smoke & Bone had too much romance may enjoy Blood & Starlight much more, provided they aren't averse to the dark and bloody nature of the storyline. For me, the thematic depth of Days of Blood & Starlight, along with the touches of romantic angst, are precisely why I'm favoring YA romantic fiction over the adult version nowadays.
Yeah, this one's a keeper.
