Gifted book through the author and Netgalley.
Sadly this was not one of my favorite books by this author.
Maybe I have become to accustomed to her character building books like her A Little Harmless series or Santini series and my expectations are to high. Maybe I put to much hope that this being a different type book that it would be equally as good, therefore causing disappointment. Either way I didn't feel a connection to the main characters, I didn't really care for Mac at all she was too closed off and bipolar. One minute she'll kill you and tough the next she's crying. I did like the man H Vic and Rock and Jay. I even liked Millie' s character more than I did Mac.
I also found the dialogue repeated from paragraph to paragraph just slightly worded differently. Why, why repeat the same things over and over again?
2.5stars and that's only because I adore this author and have loved all her other books I have read. If this turns into a series I don know if I'll give it a chance. This in no way means I won't still read this authors work, one mediocre Apple and all that.

A difficult case reunites ex-lovers Mac and Vic and teaches them exactly what they’d been missing while they were apart. In the spy world however, everything is shady and nothing is what it seems—this is at least what fiction tells us, be it in the movies or in books and whether art mirrors life or not isn’t quite the debate here really. Melissa Schroeder writes a pretty convincing suspense and it’s a story that takes off from the very first page, although I found myself rather disoriented without the groundwork and the name dropping that came in the first chapter.

Mac/Vic’s split because of a difference in opinion along the their constant fighting made for an interesting second-chance kind of novel because it involves 2 very jaded people who actually know the score, having been in the game for a long time and play an on-off relationship the way they want. There’s definitely some kind of secretive James-Bond vibe to it, yet I had a hard time getting invested in all of the characters though and not just the protagonists. Mac/Vic’s push-pull status throughout became off-putting, and they way they perceived their so-called relationship as a game so callously played made me wonder if they actually were compatible at all beyond sex. The ‘serious’ evaluation of their relationship comes in this book somehow lacked the delicious tension that I normally look for, and Mac/Vic’s scenes were peppered with more regret and caution than the fresh, exciting feel of a new relationship as they work together this time around. It’s definitely mature, more adult though—and probably appealing to others who are tired of teenage shenanigans in their adult protagonists—but I wished I could have summoned more excitement about them.

The long and short of it, ’The Boss’ is probably not quite for me, even though I do like what romantic suspense has to offer.

Vic is so use to being the boss, that it comes naturally to take control of circumstances and expect people to follow orders. Now he has to learn to work alongside others or risk losing Mac again. Mac has been hurt so many times, that trust comes hard for her. But in her job if you can't trust the people you're working with then you're screwed.
The Boss is a kick-ass suspenseful romance with a second chance at love for Vic and Mac.
