I noticed that you didn't include your stand-alone, Letting Go, although Casey and Devlin both have roles in Absolution, and we meet Jonas for the first time in Letting Go. I know that I had to read through all of the book descriptions to find this connection when I first read Absolution (I remembered encountering the characters mentioned, but not a lot of the details). Knowing where to go for some of the backstory might be helpful for new readers.
Hi Jennifer, that's true, I didn't include the connection to Letting Go because it isn't part of any of the series. I purposefully don't advertise the connection because that book was the first one I'd ever written and isn't as strong as the others. In addition, it is mf which most of my readers don't read so I made sure to write Absolution as a standalone.
