Books where two (or more? if these exist I WANT THEM) characters are bound up in some way—inside each other's heads, connected by a spell, entangled by technology—the important part is the forced proximity and the element of technology or magic, or something else over the top that would not normally happen! And maybe they're in love or they fall in love as well...
100% open to recommendations, I want to know about ANY books you think might fit 🙏

I know there are more books with this trope/dynamic I'm forgetting about AND I'm desperate for more books that might fit this because it's soooo specific and I eat it up every time so PLEASE if you know of any books, TELL MEEE 🙏
The Archive Undying!
Ohhh that's SUCH a cool premise for a list! AND YOU ALREADY HAVE ASUNDER ON IT, AHH THAT MAKES ME SO HAPPY!
I'm combing my shelves for suggestions, but - I don't read them myself, but if you look for mate-bond stories you'd probably find a bunch of this? I'm assuming, I guess authors are going to vary in how they write it.
Saint Death's Daughter by CSE Cooney has entanglement between Lanie, the main character, and her zombie nurse/servant. It's mostly because of Lanie's bloodline and also being a necromancer. I'm not sure it gets enough page-time to qualify for this list, though.
Oh! The Tarot Sequence by KD Edwards has this between Rune, the main character, and Brand, his bodyguard. They're very happy to be entangled like that, though.
In the Black Dog series by Rachel Neumeier, Natividad (one of the main characters) accidentally creates this kind of entanglement with two other characters (they can both sense her, but not each other, so it's not PROPERLY three all bound together).
OH OH OH!!! I'm such an idiot, how could I forget! The Unspoken trilogy by Sarah Rees Brennan! The two characters have been talking in each other's minds since birth, assuming the other is their invisible friend. But then they meet in real life. It's nothing like what you're probably assuming, they don't immediately fall in love or anything (they're actually horrified). Alas, it is YA, but I recommend it anyway for the entanglement trope!
In SM Stirling's Shadowspawn trilogy, this is a thing! One character gets kidnapped by a sort-of vampire, and being repeatedly bitten gives the sort-of-vampire access to her mind and whatnot. It's played for creepiness.
I'LL ADD MORE IF I FIND THEM
