This was a reread for me, and I enjoyed it just as much second time around. It’s a sometimes brutal, sometimes touching, often very funny western that plays like an offbeat version of True Grit, with the “offend everyone” sensibilities of late 90s/early 2000s comedy. 
It features a youthful protagonist on a quest to rescue his sister, a cast of characters that manages to be both eccentric and very likeable, some decent action and a charming found family vibe. 
All in all an enjoyable and satisfying read and a great introduction to Lansdale if you haven’t read him before.
