Yes, the wait is hard. And the dread of seeing the end looming ever closer is even worse.

If you reach the point where you caught up, I highly recommend the fan books with good background information to tide you over. The side story collections were interesting too. Not on the same level as the main story but they fleshed out some of the side characters and what was happening behind the scenes when Myne wasn’t looking. It’s not much but when waiting for the next volume I take what I can.
