I personally have some problems with this series and I realy don't see how it is similar. Sanderson's trademarks are hard magic systems and deep understanding of character motivation but neither is realy apparent in any of Throne of Glass(magic tends to be fairly emotional in nature and individuals who are not the main character kind of move around and do things for less then explicable reasons). I also find that Maas struggles to write convincing male characters something that at first made me laugh but eventually got kind of annoying(same as with female characters).
Excellent choice. Role reversal, deep character understanding, an interesting magic system, and a lot of heart.
For my own picks
The Goblin Emperor(It is a bit like Gawx's situation actually).
The Name of the Wind(If you are willing to wait for the 3rd one to come out. Excellent writing).
Switch things up and try some sci-fi. David Brin's uplift series is great. Same goes for the three greats Clark, Heinlein, and Asimov. Be prepared for some dated representation of women. That is equally annoying if somewhat more understandable(Some of this stuff is over 50 years old).
Alternatively ask the owner of a local bookstore or a librarian for some recommendations. These are surprisingly knowledgeable and too often undervalued mini gods of literature that should realy be considered.
