I really enjoyed how well thought out and realistic their relationship was. These two come across as real people with real problems. Michael is not an omniscient dominant and Sarah is not a perfect picture of submissive bliss. These two have problems and together they work through them.
I would recommend this book to anyone those who are new to the submissive lifestyle as well as those who are a bit more experienced. Realistic relationships, believable characters and some neat domination games/gimmicks make this a very enjoyable read.
