Why This Must Be Read: This story is epic. It is a complete retelling of the Lord of the Rings saga with Tim Drake and Cassandra Cain inserted. Moreover, it's done well. Cass and Tim are 100% themselves, and the comics, book, and movie canon are melded together nearly seamlessly. Moreover, the relationship between Cass and Tim is so beautifully organic in the way that it begins, grows, and develops. The story is also breathlessly addictive, and even those who know the framework of LotR will get a few surprises. Basically it's... epic.
