I loved books 1 to 3 in this series. Out of all the BDSM novels I've read, this series had the most strict D/S relationship. Tobias takes on Noah as a sub after seeing Noah needs something, he's adrift and needs grounding and issues dealt with. Tobias is a sucker for a sub in need and something about Noah entrances him. Noah is not a sweet yes sir sub all the time. During the day he's a police officer and he has to work to weigh up his responsible professional life against his need to give up control in his private life.
I thoroughly enjoyed reading the start of their relationship and all the details of Noah's training. Tobias is not a know it all dom and goes to his friend Bradford when he needs to who then uses his dom nature to help Tobias.
It's not all cut and dry D/S split between Noah and Tobias and that does not detract from the power exchange you can feel. Tobias is strong enough to admit that sometimes he needs to swap.
The walking to heel training was painful, hands over nipples to protect myself while reading that, I was in awe of Noah's courage jumping in a contract with the infamous Tobias, and watching him flourish was beautiful.
The pride Tobias felt when Noah achieved a task or overcame an obstacle was fantastic, you really understand what he as a dom gets out of training a sub and the descriptions of Noah's feelings explains what he gets out of it.
They are a great fun couple and their rough and tumble and often funny role playing games were hot, sexy and great to read.
