AC Crispin is a fantastic female sci-fi writer who put together a way better plot for young Han Solo than the Solo movie (shocker, I know)
Three books, they have him meet and work for the Hutts, have his first run-in with Boba Fett, have his falling out with Lando, etc.
In the first one, he is basically an indentured servant to a low-level crime lord. The guy has an elderly female wookie as one of his servants, and ends up killing her, which is Han's last straw to escape. He winds up flying cargo haulers to a planet that has a major league cult going on. He rescues the hottest girl there, probably bangs her, but she splits.
The second one is really good, with it being several years later; he's rescued Chewie off screen and both joined and dropped out of the Imp academy. He starts working for the Hutts and has a surprisingly fantastic relationship with them, bangs a couple of hot women, runs afoul of Fett, who gets taken out (temporarily) by Lando of all people, and totally screws Lando out of the Falcon.
In the third one, he reunites with hottie from the first one, ends up helping out with an early Rebellion scheme in which hottie promises him a huge cut of the loot they're stealing and that she'll leave with him; but does neither, steals the loot and has Lando and others out to kill him because he promised them all a share.
