Would it still be considered "trade", if main character and 3rd generation "truck-driver", Jack, exchanges his sexual favors for stuff with the giant women?? Or has the author "whored-out" the main character already?
Because it's a "trucking" theme, the author actually considers using the truck to travel to the different worlds, the thing is Teleportation/Portals 101 usually say that the "heavier the load (weight of the people and things that travel) the heavier the magic/crystals/mana/energy costs... So, what would be the cost of a loaded rig +3 beast-women+Jack??? Isn't it more expensive this way?? Why not use "space-rings" or other weight saving technologies readily available in most fantasy novel series?? Didn't the truck get damaged on his first trip to another world?? Is Tor going to take in the rig the necessary spare-parts to fix anything that could get "broken" in another-other-world??
The more one thinks about what the author writes, the less this story makes sense. I think a story like this one would have been better seen/read in a comic/manga/manhwa version (a lot less talk, less plot holes and a lot more illustrations)...
Kudos to the author for not making all of the sexual scenes incredibly graphic...like I've said before written erotica is a lot less pleasant than having "real sex" and less visual than just watching porn... Although harem-lit is a niche, there really is no idea of seduction, of actual conditions to have a guy get several girls interested in him. (Power, money, security, improves genes, etc.) and a "trucker-guy" like Jack, is nobody's slice of pie...Jack does not meet harem conditions in any of the different characteristics and the delusions of the author, awarding him with 3 incredibly beautiful beast-girls, plus giant amazonian women and other "conquests and sexual transactions", makes all of it illogical, nonsensical and irrational...It's as if the author is pro-actively spreading Sexually Transmitted Diseases(STD's) in the Universe (especially if stupidity can be considered a "disease")... The fact that an author like this one, thinks that a promiscuous woman will "naturally" have lesbian sex with anybody, and the protagonist, shows how little to none emotional intelligence the author and main character might have... It's as if, the author would instantly go into a homosexual adventure(s), just because a "hot girl" offers him a threesome (M-M-F)... Are authors a reflection of the fictional characters they create?? If the characters are all promiscuous and slutty, does that mean that the author is the planet's slut too???
The first trucker book is one of the best cover illustrations that I have seen/read...This second one, seems adapted from a photograph, but not as good as the cover illustration of Book 1. Book 2 is as short as book 1, they read like a light novel series without the maps, without the inside illustrations, without the character summaries, or the side stories...
The last 1/4 felt like a re-run episode of Buffy the Vampire Slayer...Weren't they traders and sex addicts in trucks??
