Saturn returns are always about learning something so you can move onto the next stage in your life. Without seeing what other planets asteroids you have in your 8th and 2nd it's hard to really access what area Saturn will be testing you in. As it's in the 8th house I would have said it is about resources but it could also be facing ones mortality and reproduction, I don't mean your gonna have to go through some near death experience or something, what I mean is it's probably going to make you address whether your karmically fulfilling your life plan, are you on track, it will force you to let go of the things that are not working in your life and work hard at learning what the bigger picture is, you don't say which sign it is in, thats another factor to check out. Would you be able to post your chart so I can take a further look at it.
Sometimes I've found it's not always what house the Saturn return is in that gets effected. My Saturn return was in my 3rd/4th House depending on what system you use. Yet the major thing that the Saturn return effected was a 13 year relationship, which ended because we were at two very different life stages one of us was on the rise and going from material success to success while i was on the downward spiral I was made redundant was suffering with depression , the relationship fell apart and I lost my home, and some of my old friends. but I found solace in building great new friendships at that time I came closer to the old me who was a lot more altruistic and caring, I also worked on building a better relationship with my mother.
My Saturn is natally opposition Moon and Neptune so the return seemed to force me to address that opposition. I'm not saying there weren't days going through it that I didn't lie on the ground crying and asking why me, but it was a serious bit of growing up and it in part got me into the frame of mind to deal with greater test in my life and to appreciate the good things more.
Saturn 8th could mean an inheritance from a elderly relative, but with it comes responsibility and makes you examine your own mortality. What legacy do you wish to leave behind in the future when you reach that stage of life, these may be the questions you will be forced to work on, Saturn is a hard but fair task master.
If you post your chart I'll take a look and see if I have any insight into what areas you can expect to be effected and suggest how best to work through this time.
