Learning the Cyrillic alphabet

What is the fastest/easiest way to learn to read fluently the Cyrillic alphabet (language doesn't really matter, but assume Russian if it helps).

It would feel badass to be able to at least read the titles of books in the Russian section of the library.

Good luck, it's an easy alphabet, but reading can be a pain in the ass. You'll have to adapt to consonant clusters in Slavic languages or else you'll sound like an ass.
