Yeah, it's an omnibus of the three Lando stories from 1983. There are two Han Solo prequel series that I know of--there was the one from the 70's that went along with the Lando ones, and there was AC Crispin's trilogy from the late 90s that fills in the blanks and gives you a bit of their joint history (and how they parted on less than friendly terms), as well as Han's history with the Hutts, why he's so comfortable with Wookiees, and the reasons he's just a tad suspicious of hokey religions. (That trilogy is the one exception to my "By Kevin J. Anderson Or Before 1996" fanon cutoff.)

I gotta say, I love Lando. He's weird, flamboyant, cheerful, and hilariously snarky. And I think he's a lot smarter than Han, to tell the truth. Plus, he dresses better.
