This story will really benefit from you having read about the characters previously in the Cut & Run series by Abigail Roux and Madeline Urban. There will not really be any intro to the characters or lead-up into the story. It takes place immediately after the events of Touch & Geaux (book 7) and before the events of Ball & Chain, book 8 in the Cut & Run series (expected release, March 2014). 
 For those unfamiliar with Cut & Run, one of the main characters of that series, Ty Grady, was a Marine on a Special Operations team. The team of 6 was called 'Sidewinder', from hence came the name of this spin-off series for two of the other team members, Nick and Kelly. 
 Kelly is recovering (from events in Touch & Geaux) in his remote cabin in Colorado. Without question, Nick goes with him to help him recuperate, since Kelly can't even roll over in bed or sit up without help just yet. After seeing Ty & Zane together, Kelly becomes bi-curious, very specifically about Nick. Kelly talks Nick into kissing him on a whim, even though Nick's never thought about Kelly in that way any more than Kelly has about him like that, before now that is. 
 Now both of them are wondering how their friendship will change because they've known each other for so long that neither one can put anything past the other. But that also means they know exactly what each other wants and needs. Is throwing caution to the wind really the best idea for them? (Well, except for the whole Kelly-is-injured-and-Nick-doesn't-want-to-break-him issue.) 
 Now, for those who have read the end of Touch & Geaux, you have an idea of what is going to happen at the end of this little interlude of theirs. Bad timing and all that. (view spoiler)[All the more reason for Nick to get his and Ty's (and Digger's and Owen's) asses home in one piece. (hide spoiler)] 
 But, there is a tidbit of bonus Sidewinder short story in the back of the book called Bait & Switch. It's a few (unspecified) months later, after Kelly has healed. (Oorah!) 
 Both stories are incredibly sexy shorts (even if you're not already familiar with the characters, but moreso if you are), and I cannot wait for Ball & Chain to come out. =)
