Is "Even so, we’ll keep walking" a valid sentence as a book title?

Question

I was struggling to find a good title for a fiction I write, and a found this sentence in the english subtitles of a song. I'd like to know if it's a valid sentence as a standalone, or if it needs to be a part of a full-lenght sentence.Thanks for considering my request.

Answer 1

This is a valid sentence, and I find it intriguing as a title. it is open-ended, with an air of mystery.
