Mistborn score - any good?

Thrift shop had a sale and I nabbed these Brandon Sanderson books for two dollars.

I've listened to his stuff on audio books from the library.   But they don't have many and the wait list is about 40 weeks to borrow physical copies (only 30 weeks for audio books) so I kind of got board waiting.  The stormlight books I read were good but complex.  Most of them I couldn't finish before the library wanted them back (dyslexia makes slow reading).

Haven't read any of this series yet.  Should I wait until I can find a copy of the first book, or is it one of those series I can jump in at book 2?

I haven't read those.
I looked them up like I would if I had bought them, and what I saw sounds like the first one is the first of the first trilogy, and sounds important. The second quad is set 300 years in the future, so if I didn't have the first book of the first, I'd start with the second set, while looking for that first book.

Thanks for that.
Putting it on my wishlist  for later.  And the Way of Kings as what I read of it was epic.  

I'm still on the dragons books.  I bought the first three and am just finishing up the second one, so I have a while.  Maybe I can find the Sanderson book second hand before I finish?  But it's unlikely as his stuff seldom comes up in the thrift stores.  

Should be finished my dragon book this week and can start on these.  Shall I go with mistborn or stormlight first?  (I kind of bought most of the stormlight partly at the thrift store partly new)

My hard-core Sanderson-fan brother says: "The Mistborn series is a little more accessible than Stormlight - I'd recommend reading the first trilogy of Mistborn first. The first book can also be enjoyed as a standalone heist novel, so you won't feel pressured into finishing the series if it's not your thing.

Stormlight is a culmination of Sanderson's work and combines several of his series. Enjoyment of it is enhanced by having read his other books but that is not mandatory. They are his longest and most world-building heavy, and may turn off some people who prefer shorter, puncher works.

I'd dip your toes in with a book like Mistborn or Warbreaker, and see what you think from there."  

Not sure if you have already started, but absolutely do not start on book 2! A big part of Sanderson’s writing is unpacking the complexity and various twists and turns. Starting on book 2 will definitely spoil the enjoyment of book 1.

Personally I love the Mistborn books. They are a good warmup for coping with the massive Stormlight Archive. Wind and Truth was 62 hours in audiobook form - fantastic value for a single
Audible credit.
