Cheshire’s Smile (The Underground Book 7) by Erin Bedford
A mind is a tricky thing. It’ll even trick you.
Well, I’ve screwed up again.
I dived head first into the Underground once more, thinking I knew what I was doing. What I got was a whole lot more than I ever wanted or expected.
With the sickness spreading like wild fire, a High King must be found to save the Underground from perishing and I was the only one who could do it.
How do you save an entire race when you can’t save yourself?
