This book is the third in the series and deals with Kim the Korean doctor we met in "Collision Course".Kim is a quiet thinker and he is well teamed up with Shane who in some ways seems the complete opposite and at others has a lot in common with him.In K.A's books most of the conflict doesn't come about from some outside source (ie murder or evil character) it comes from differences in the characters personalities and their past. It is the way these characters, who invariably have straight up physical attraction, morph this into a stronger emotional connection that make her books so enjoyable to read.I think it was this paragraph that took my admiration from four stars to five:"Kim found the soft skin behind Shane's ear and licked down to his collarbone. He swore just the taste was enough to get him hard. He was going to have to apologize for laughing at that article on the vomeronasal organ in adult humans because this had to be pheromones. Nothing else could explain that one taste, one breath of his skin made Kim want to bury himself in this man, wrap himself in Shane until it was all he ever touched or tasted.", [K. A. Mitchell, No Souvenirs:]Thoroughly recommended.Edited to add. I just read this again and have moved it up to my favorite K.A. Mitchell book and one of my favorites of all time. There is so much to appreciate on the re-read, the reef scenes, the pacing, that difficulty for both men to open up to what was going on inside. The sex scenes are superbly written, only enough Slot A to Slot B being given to create a picture, the whole emphasis more on the effect it had.In some ways, it is better writing than "Collision Course" as re-reading brought out lots of little "shows" done in simple sentences that I missed on the first reading.The descriptions of scenes are so well done and well integrated into the story.Not a DIK but a scarily small reef keeper.
