I think a great title should evoke mystery, adventure, or a sense of wonder. 'The Shadow of the Forgotten King' has that epic, timeless feel—like you’re about to dive into a world of ancient secrets and lost legends. Another favorite of mine is 'Whispers of the Celestial Blade,' which hints at both magic and destiny. For something lighter but still enchanting, 'The Tea Dragon Society' (though it’s a graphic novel) is utterly charming.
If you want a title with a touch of darkness, 'A Crown of Crows' immediately sets a grim, poetic tone. Or go whimsical with 'The Library of Lost and Found,' suggesting hidden realms and untold stories. A title should tease the reader’s imagination—like 'The Last Unicorn' or 'The Name of the Wind,' which are simple yet unforgettable. The best ones linger in your mind long before you even turn the first page.
