I love you. I love you. I love you. I’ll write it in waves. In skies. In my heart. You’ll never see, but you will know. I’ll be all the poets, I’ll kill them all and take each one’s place in turn, and every time love’s written in all the strands it will be to you.

This is one of those stories that will weigh on your mind for a while.

I can't say much about the content itself for the sake of spoilers, but at its heart, this is a story of love undefined by space, time, and every other human limit. It's written almost exclusively in poetic and lyrical language, dominated mostly by letters shared between the characters. I typically have a love/hate relationship with purple prose, but I didn't mind it too much here because...wow, I'm a bit jealous, to be honest.
I won't officially rate or review this in my usual manner because I don't think I can come up with numbers or words to describe this story, but if you're a fan of unique story formats, romance and time travel, or lyrical prose, I would highly recommend you read This is How You Lose the Time War.
