I've read many books from Brandon Sanderson, the Mistborn series with the Alloy of law following, and then the wonderful Stormlight archive, these are some of my favorite books, and I am awaiting the following books eagerly. Which I know will be coming (looking at you Rothfuss). I would love to recommend these books, but the commitment is huge, definetly worth the investment, but it's hard to recommend someone to make that investment, because the story does not start straight away, and the information is distributed carefully.
It is hard to recommend a book, it is a quite personal thing, to recommend something that is close to you, with a high likelyhood for the other person to simply not to like it. And books have this sunk cost falacy, I am not sure why, there could be a few reason or a combination of those :
Someone has to pay for it. Either you pay for it, or it's a gift. People don't like to get rid of gifts.
It is made of physical matter, humans can be too attached to physical stuff, paper is paper, when it has left the library it has no longer the same value. Most of my books are on the Kindle or audiobooks. And the ones that aren't, it's because I need to work on them, like writing stuff on them. Paper is the same as a piece of wood, please don't value it because you think it's special, in most cases books are printed in many examplaries.
You've started reading it, you need to finish it, else you'd never know the end. I believe it's the writter job to keep you interested, if you don't like it, stop !
Now, finally as for the reason why I decided to ramble here, and continue to ramble. I've started and finished Skyward), and it was so different from the other books, much less epic in a way, but so gripping, and fun, and engaging. I love the author, because I rarely know where things are going, or because the character traits are compelling. I hate characters that are just petty or bullish, or when they just do stupid decisions. Robin Hobb books are somewhat like that not the Apprentice trilogy, but the one with the boats, quite frustrating sometimes. I finished the Mistress of the Empire from Raymond E. Feist, just last week, and I had to jump the start, for there was no way the character would act like that, or act so rash. And I know the argument can be made that sometimes people break, but the character had previously acted so differently, and was admired for her calm and logic.
Anyway, I loved Skyward, it's easy sci-fi to recommend, and I should not have waited that long before getting it !
