The Selkie's Coat is the first book in the Waves of Fate series and we start off with a seal (obviously!) shifter and a human omega. In this omegaverse, shifters are common knowledge, human omega's are rare, and new things are being learnt all the time.
Gregory is amazed to find his fated mate when he is so young - only 100 plus years - and is determined to do the right thing and give his human mate a chance to learn about what a fated mate is. This goes against what his inner animal wants to do and causes strife between the two of them. Daniel hadn't known a human omega could even mate with a shifter so the whole thing came as a surprise to him. He is fascinated by Gregory, even more so when he gets a glimpse of his seal speaking through Gregory's human body. Understandably, though, his feelings swing like a pendulum as he doesn't understand just what is going on.
This is a lovely slow-burn romance with a sweet Alpha and a headstrong Omega. Sometimes I wanted to whomp Daniel upside the head as he seemed to swing so much and vent his frustrations on the wrong person. Don't get me wrong, I liked Daniel but sweet Gregory was the one I fell for.
One thing I loved straight away in this book is the amount of shifters here - and it's not always cats or wolves! Scenting their mate is a big thing in most paranormal books but in this one, because Gregory is a water shifter, for him it's the sound of Daniel's voice. I loved that!!! The oh-so-simple idea that different shifters have different ways of knowing their mates.
