I'd do nothing but reading if I could (ok, maybe eat some great food, buy some fancy shoes between two books...oh, and spend some quality time with the gorgeous guy I married while I am on reading-break anyway...)
I liked "Beyond Duty" where the couple, Mac and Gunny, made a first appearance.
This short sequel - not as much.
It was a bit sappy, a bit over-sexed, and basically revolved around them going to experience a real life BDSM-Club.
I am not into BDSM, so I found that part a bit boring.
It was free and short, so no big disappointment.
