4.5 stars. This James Bond-like thriller definitely hit all my action-adventure-romance-m/m buttons in one go. Really really fun read, quick pacing, and interesting, engaging, and sexy main characters with great chemistry. I appreciated that Sebastian wasn't so helpless, and often his ingenuity would surprise Kyle-the-super-Spy. Sometimes I did question the sexy times happening (like, "Really, guys? Sexy times NOW??") But whatever--more fun to go with the flow on this one. The ending leaves a potential opening for further adventures, so if the author so chooses, I would definitely be up for following along for more Action-Adventure-Super-Spy-Romance-M/M Awesomeness.
