I do not typically do reviews for books I give 4 stars, because +/- 1 star still puts it in "probably worth reading". I am going to list some thoughts on the ENTIRE series for future reference.
1st and foremost, I feel books 1 and 2 should have been combined into 1 book. Nearly all of my issues with book one would have been fixed if they were combined. It made so much more sense after finishing book 2. Plus, I think combined they would not have been longer than books 5 or 6. So... If you were not thrilled with book one, I highly suggest reading book 2 before deciding on giving up on the series. If 2 had not already been out, I might not have continued. I'm really glad to have read this entire series.
2nd, Unless you have a great memory, I highly suggest you read these back to back. The entire series is out. I felt it got mostly stronger as it went along.
(* Even reading back to back, due to the sheer number of characters plus characters with similarly spelled names, I was glad I was reading on my Kindle. It was easy to run a search for a name to be reminded of who they were etc...
3rd,I thought the progressions for the characters and the overall plot moved well. It never felt repetitive except where it should, like when reminding the reader what has happened previously.
4th, I really liked the concept of shifter cowboys.
5th,the world building was extremely strong.
6th, those that do not typically like m/m/m or mpreg, please consider giving this series a chance. It is not the main focus until really late in the series, and it is done really well. FYI, for me personally, I can take or leave either one. Not something I look for neither am I really opposed to it.
7th, I did think the proofing / editing seemed to be not as strong. I noticed my flow being disrupted more often, but never enough to hamper the enjoyment.
8th, I felt the final book wrapped up all major things and most minor things very well. It definitely ended on a HEA for our m/c's and most supporting characters too.
9th, the only thing that gave me pause in the whole series was the brother's storyline, especially in the last book. It wasn't poorly written or necessarily out of character, but I did think his twist could have been better supported or explained. To me, It did feel more conjured for the plot than organic, if that makes sense.
This was a really good series. That definitely should be read in order, and as mentioned earlier probably back to back. The plot never gets stale or meanders inappropriately. All central things are moved along well and tied up by the end. Well worth the read if you like shifters, mythology, royalty, epic adventures etc...
