The title almost put me off. I'm glad it didn't. This is a good tale of a bond between a human and a sentient bott. There is a lot of "frolicking", but done in a tasteful way. There are twists and turns that makes it read like Matrix on a rollercoaster! The latter part of the book deals in fantasies experienced by Zach and Rosie, and can be skipped or dipped in and out of without issue.
I read this book via Kindle Unlimited, but have the others cued up and ready to go.
If you're fairly broadminded and don't mind a bit of thinking with your reading, go for it :)
