Horde accomplishes everything that the third book in a trilogy should: It ties up all the loose ends, answers all the questions (specifically about the Freaks; I loved learning more about their origins), and in the end does justice to each of its central characters. It's a tale of violence and brutality (the battle scenes are truly epic; Aguirre did her research, and it shows), but also a tale of redemption and hope and, ultimately, peace. And the epilogue? It was PERFECT. It gave me goosebumps and a lump in my throat. 
 I don't love Aguirre's writing: Aside from a few flashes of brilliance in particularly insightful passages, it has a tendency to feel clunky and clinical, and some of the chapters end in awkward places (like in the middle of conversations). But in an epic trilogy like this one, it was easy for me to overlook that and just be swept away by these amazing characters and this amazing world Aguirre has created. I definitely recommend this trilogy; it's solid from beginning to end.
