All I have to say after finishing this is - WHEN IS THE NEXT BOOK COMING OUT?! (I know, it says spring...but that's soooo far away!) I want it now!
This was, in a word - excellent! We finally get answers as to why Edward's father acted the way he did, towards Edward, Percy, and their child. And wow, it's a doozy! And I LOVED Reynard and Mason together, I was glad that we got so many different POVs in this so that we knew what was going on with everyone.
But above all else, I loved Percy in this one, since he really was gaining confidence and becoming his true self in this one. He spoke up for himself and definitely had more personality than the previous stories. And this is probably my favorite mpreg series, since it just kinda...works. It's explained genetically, scientifically, and it just all works for me. It's a modern day story, but set in a different world. And he and Edward are totally, ridiculously hot together.
You definitely have to read these in order since they build on one another and is a continuing story, but I say give this one a try!
