There is a lack of communication in this story, between all characters. When the guys hold back their secret, but still move forward physically with her frustrating for me.

Tiff is a bit of a pushover who thinks of standing up for herself but only does twice in the book. 
Leon, the eldest is a what the author calls a soft dom, taking charge and leading Tiff in taking what she wants.
Jace is supposed to be the funny, goofy one, but I didn’t see that in this book. He actually got pushed to the wayside multiple times in this book.
Quinn, is the youngest and the silliest. He is so earnest and cute, you can’t help but love him.
Eli goes from the sweetest one, helping her during an attack, to being unnecessarily standoffish and we never get a true understanding why.
