Daggermouth is the sort of title that sets its register before a single line is heard. H. M. Wolfe writes at the darker edge of romance, where the love story cannot be separated from the world threatening it, and our shelving reflects exactly that indecision: fantasy, science fiction and romance all lay claim to this name at once.
The billing as the opening half of The Heart Duology matters more than it might seem. A duology is a promise of shape, of a story built to close rather than to run on indefinitely, and it suggests a writer who knew the ending before the beginning went out. Beyond the work there is little on record, and the work is unambiguous enough about its intentions: high stakes, morally compromised characters, and no appetite for a gentler version of either.
