I received an ARC edition of this book from the author.
Alex may have been a low caste dragon like his brothers, but his unusual coloring meant he was raised among one of the ruling families. When his foster family proves to be a threat to his new home on Earth, Alex is willing to risk everything to stop them. Nicole can understand growing up in a crazy family, her own family certainly has had it's drama (see Amber's book for more on that!). She's been a bit adrift lately in her life, unsure of where and what she actually wants, but dealing with a psychopathic dragon matriarch and an emotionally distant dragon she might be falling for definitely weren't on her plans.
This story was a bit more drama and danger filled than the previous books. While all of the brothers have had their issues, Alex certainly had a very dangerous upbringing and it made it very hard for him to be willing to open himself up emotionally. Nicole has her own issues with self-worth and trust and it plays a part in how she and Alex interact. The two of them made for an unusual couple, and I wasn't sure how they'd actually work long term at the beginning, but by the end of the story I had warmed up to them as a couple.
