Neverfall - Brodi Ashton
This was more of an explanatory novella, where we just began to understand why Cole choose Nikki as his forfeit, but there’s also another part of this novella that tells more about the reasons for Cole not to give up on Nikki even now that Jack is gone.

Cole wants to overcome the queen and stop paying the taxes, but we can also see that is way more than just that and he actually became emotionally involved with Nikki way before she could survive the tunnels. I believe she became his obsession because of her feelings like a pure and simple disease for him.

I liked this novella and how it tried to shed some light on Cole’s feelings and reasons now and then when he took Nikki to everneath. Nice touch of the author to spread some knowledge
