I used to not be able to DNF a book. I always felt like I had to finish it. That has thankfully changed.

Thanks! It's progress for me. I snuck a peek at some of the reviews and so many of them said that Miles' POV chapters were almost always in the past, dealing with his dead ex, and that was pretty much what killed it for me. Some flashbacks for backstory are fine. But one character living in the past? Nah, pass.
