I recently finished the 7th book in the Wheel of Time series, A Crown of Swords. I am currently contemplating whether to start book 8 or read something else to not get burned out. A Crown of Swords is the first book in the series I did not enjoy that much.
Definitely take a break! That's about the spot where most people struggle to get through. Take your time; there's a lot of setup, but the pacing is not great.
Also, I think book 8 is The One Without Mat, so it took me forever to get through it.
