The Elvenbane (Halfblood Chronicles #1), by Andre Norton , Mercedes Lackey

I tried. I really tried. I was even going to finish the book, since I've abandoned a few in the last few weeks, but I just couldn't go on. It was clear that none of the major story arcs were going to have any closure by the end of Elvenbane and I couldn't care less about any of the characters. It was trope after trope after trope, a female lead who seems to have no flaws and always falls on her feet - mostly because of innate attributes or luck, mustache-twirling villains, everybody is oppressing women and young ones in particular, dragons, elves, human mages, even a brother-sister infatuation, to just catch every single cliché. The world building was shallow and the focus of the book was instead on ideas on how the world should be, what is fair, who is attractive and who is not and so on, their feelings.
Basically, this is a young adult fantasy from the '90s: too old to face Internet scorn and too new to be actual fantasy and not derivative corporate bookstore slop.
Not even sure who wrote what. The book I have says it's written by Mercedes Lackey. The online says it's Andre Norton, sometimes with Mercedes Lackey, both women, only Norton was 80 when the book was published. Honestly, I don't care.
The problem I have most is that the plot is inconsistent. I don't want to get into details, but there are many jarring events that just contradict whatever happened before. Simple example: the magical Mary Sue teleports with her mind a big deer for food. Apparently you can do that, but the result is instant death for the animal. At no point in the book does she do that with any of her enemies. But there are bits where she smugly teaches people what they could do with the little magic they know.
Bottom line: the occasional bright spots were not worth slogging to finish this book. It's derivative, tropey, amateurish and could have been edited to half the length. Feels like a publishing house money scheme.
