Dissections of finite groups and their associated covering groups, projectors and normalizers

Very Big! I spent a lot of time babysitting my brothers while my dad was writing this. A lot of time! Hopefully, I'll be the one to inherit some day, although shipping it over here would be a pain because it's two volumes. I've never read it having only a rudimentary grasp of mathematics. I think I got my mom's genes.
Anyway, I can't tell you what an honour it is to be related to this genius. It's unfortunate that none of his kids got any of his brains.
