One of the possible solutions is to stack up your book clubs (so they can haunt you later!).
You can participate in, let’s say, 7 clubs, then basically you’ll have to read one chapter a day in a week. It’s about 1-1,5 volumes a week.
Or you can join intermediate clubs too, they read faster. Twin spica is only level 24 for example.
There’s a very cool master list of book clubs to choose from
