This tome contains all the stories, plus artwork of bounty hunter Mercy St. Clair, as she fights not only criminals on the lamb, but the corrupt police and politicians running New Galeph.
These tales aren't all about blasting bad guys. Mercy is a troubled woman, riddled with as much doubt as her body gets riddled with bullets, while seeking to find a balance between her rough profession and her softer personal life. There's a "creation of Mercy St. Clair" chapter that involves a mentor and an old flame.
The stories are well written and well drawn, although most of the images are in black and white.
Speaking of imagery: While athletic and attractive, Mercy isn't a overly-buxom babe in a skimpy costume. Oh sure, there's usually a picture or two in each chapter of Mercy in a nice dress, while out on the town, or even in lingerie; but her trekker (bounty hunter) uniform looks more practical than just about any other comic costume I've seen.
If you like retro-noir sci-fi with flawed female protagonists then Trekker Omnibus will be a good read for you.
