This story just completely sucked me in, to the point that I am really glad I didn't have much else to do today so I could just spend time reading it, as is necessary because it's - ugh, good. There are moments in this that are really very sad, but how can you have a ST fic involving Tarsus IV and Jim's resulting trauma and not have there be any sad? It's also quite beautiful. And it convinced me I really do need a shelf for bonding stories.
Spock felt almost bad that he could not explain Jim better, but he was aware that every time he attempted to explain he ended up making Jim sound bad. He had tried it in Standard, in English, and in Vulcan, but he could not find the correct words. Could not find the word they could accept—he had a feeling that his mother would be very displeased if he told her Jim was t'hy'la.
I absolutely loved it and can't wait to read more by the author.
Spock had lived all of Jim's trauma second-hand. He had found solace in the eye of the hurricane, taking advantage of the way Jim could keep everything at bay. I know you, he thought. I do not want to know who I am without you.
The writing isn't perfect and there are some typos but it's still great.
Edit: initally didn't add this quote cuz I typed this up just before bed and clearly I shouldn't do that since I come back and remember stuff I've forgotten, but - quote:
