I'm gonna give it 4.5 stars, and I'll round up once I determine rereadability. 
 If you're looking for something like Mary Calmes's Change of Heart series, it's similar in some ways and different in some ways. In CoH, true mates are pre-destined (and may never run into each other), whereas in this universe mates are chosen. In both, they are just as powerfully attracted to each other once the mating bond is in place. But where Jin Rayne (CoH) wanted to fight against his mating bond, Quade took forever to even recognize the one he wanted as his mate. 
 I have to say, I really loved Roman. He was scarred by a fire as a teenager and has come to terms with how he looks and who he is. He's confident, except where it comes to letting Quade know how he feels, because he knows Quade wants to run from his attraction to Roman. Quade's been Roman's bodyguard for eleven years (pre-accident), and so to Quade it feels like betraying Roman's father's trust, even though the man died several years earlier. But Roman knows what he wants and he's just as possessive of Quade as Quade is of him. Roman is no meek flower of submission to the more dominant Quade, even if he is 19 years younger. 
 Quade also happens to be a legitimate alpha heir to his pack of jackal shifters, but his father threw him out of the pack when Quade came out as gay as a teenager. Now there's a psychopath leading the pack and Quade's sister has come to find him to get him to come home and challenge for Alpha. But that leaves Quade in something of a bind, because his heart is back in Maine, with Roman. 
 Certainly not the most unique of shifter universes (though there are many different shifter types in this universe), but there are some interesting side characters whose stories I look forward to reading.
