The Boy with the Painful Tattoo - Josh Lanyon

I liked this one more than the previous Holmes and Moriarity books. The mystery part was quite interesting, but what I really loved was the new relationship dynamics between Kit and J.X. They behaved like real, faulted and sometimes emotional human beings

, but managed to solve their problems rationally - a good example of how a relationship should work

(show spoiler)

. I hope there'll be more books in the series...

 

PS. The guest appearance of Adrien and Jake was very much appreciated! :)
