4th Book title

Alright guys, place your bets! What are you thinking the title of the fourth book would be based on your own personal hopes and dreams for the plot -

I’m thinking something along the lines of Red River (red being venin and river being the rivers that separate the Barrens to the rest of the continent). Perhaps even Red Death? I’m definitely getting red vibes for the next book!

Edit to add: Forgot that the next cover is very much tipped to be silver - so going to add Silver Wrath if the next book is about Violet coming into full power to defeat the pesky venin like the absolute exterminator she is.
