Really not as good as I hoped...
If I didn't start reading the book so early in the morning, late into the night, and constantly throughout the day, I'd have been tempted to make this book a drinking game. Take a shot every time the word "thigh" appears in the book. (For the record, "thigh" comes up 46 times and "thighs" 87 times, for a total of 133 shots in a 453 page book.)
I admit I nearly DNF this book quite a few times. It's about 450 pages, but there's a whole lot of nothing that happens. 45% in, we still don't have a good idea of who the characters really are aside from the guys being "solid and unreadable, confident and cocky, warm and steady, and silent but present." I actually started putting the book down to choose something else but skipped ahead a bit, saw something kind of catch my eye, so decided to keep with it a bit longer. It wasn't anything interesting, but I'm stubborn and I hate not finishing books. It's a gift and a curse, my stubbornness.
When the last members of the pack finally complete their bond with the FMC, I still wasn't feeling it. One character in particular hadn't had any time with the FMC one on one at all on page, and I didn't even feel he really liked her until after the fact. By the time the book came to an end, I still didn't feel much of a connection with the characters or see much of one between each of them, either.
I personally felt the book didn't get exciting until about 75% in. I told some fellow book friends that I was sticking it out, that I was sure that once I got over the hump, I felt it would be better. I just didn't expect the hump to be three-quarters of the book...
One more small, specific critique I have is that it could use one more round of editing. It's nothing serious, but some words and names are misspelled (eg. "he" instead of "her," "The" instead of "Theo," "mind" instead of "mine," etc). Nothing crazy, just small things that an editor or proofreader should have caught.
With all of my critiquing and negativity, I'll at least end on a positive note by leaving a sweet, inspiring quote from the book:
“Sometimes it takes strength to stay and fight. But sometimes...” I pause. “Sometimes the bravest thing is just knowing when to stop giving something your attention. When to leave.”
