I recommend Breathless. 
 ...Oh, Brigid Kemmerer. You sneaky, little.....! Holy sh*t. Nick Merrick!!! 
 *breathes deeply* 
 I didn't expect this kind of curveball from Brigid Kemmerer. Really, I didn't. And now, I wish Nick's full story will come out sooner rather than later! Here is the responsible Merrick. The peaceful twin. Wouldn't you know, there's a hurricane raging silently inside of him! 
 Breathless briefly showcased Nick's role to the Merrick Family. How being the middleman among his brothers helped him help Quinn with her problems. Me thinks Nick is going to be my favorite Merrick brother, once his story is published after Hunter's. But for now, he's coming really close to Chris, who is my current fave. :) 
 So.. secrets, huh? How Brigid Kemmerer managed to write Nick's POV and he came out as hot as his twin, Gabriel... astounding.
