In the absence of a sequel, do you know of any good Let the Right One In fanfiction?
Nope. I don’t read fanfiction. I’ve read like 2 ever, not counting ironic readings of bad/gross ones.
I’d honestly sooner just read a different book that captures a similar mood, but thus far I haven’t found one - not even Lindqvist’s other books compare to LTROI, sadly.
