Summary: The marks that appeared on nearly every human one day weren’t very obvious -- a pattern resembling the whorl of a fingerprint and almost as unique, on the inner wrist, tinted the color of coal-black ink. Almost as unique, because everyone was supposed to have a match somewhere on earth, and when the match was found, with a solid press of bared wrist to wrist, mark to mark, the pattern disappeared.
Why I like it: This is a wonderful take on the now common soulmate tropes where marks identify the people meant for each other. There is a cool worldbuilding idea here, that this is not just a concept that always existed, but something that suddenly happens to the whole world and media and people react to it in different ways. Tony, of course, is a skeptic - Steve, on the other hand has already lots of other things to deal with and it seems the super soldier serum makes it impossible for him to even have a mark.
The build up for the misunderstanding was really nicely prepared and it all grew nicely out of the characterization and out of their personal issues. It's a very fund and sweet read that I can heartily recommend.
