I have read a couple of good series by Brandon Sanderson. Both are worth reading. The first series is the Mistborn Trilogy.
These books are long, really long. I read the books several years ago, so the details are a bit fuzzy. I know there's magic involved. And some kind of fighting. And a tough girl. And I remember liking the books. For more detailed reviews, you should probably click on the link and look at Amazon reviews. These books are not appropriate for children; nothing bad that I remember but written for adults.
Type of Book: Magic Fantasy Adventure
Rating: At least a 7/10, but read too long ago to be more accurate
The other series that I really liked by the same author is completely different.
You may not think that there can be such a thing as evil librarians. You would be wrong. (I guess I'm lucky that I don't have a library with evil librarians lurking around. There's no place to hide in our county's bookmobile.....) The Alcatraz books are really funny. I laughed out loud many times. These are books for older children, teens, and adults.
Type of Book: Modern Alternate/Hidden World Adventure
