Books/Advice for My Parents Over 50 who lost jobs?

I have two families: one with my biological mother (54), step-dad (56), and younger adopted brother (12); the other with my biological father (55), step-mom (50), and two younger brothers (19, 16). Tragically, since the recession all four of my parents have lost their jobs or taken a serious pay-cut/demotion that has drastically altered their lifestyle for, in their opinions, the worst. At one point they were all making six figure sums in their careers and now they are squeaking by on almost nothing and are having a tough time of it and what to do next. One family will need to sell their nice suburban home and is exploring options perhaps internationally. Everyone lives in Southern California.

I was wondering if anyone knew of a book(s), seminar, magazines, or any other resources that could provide them with credible advice and information about how to reinvent themselves and explore different lifestyle and career options that will leave them fulfilled. All of them are in their mid 50’s, in relatively good health, intelligent and morally upright.

I have told them this is an unexpected opportunity for them to change a monotonous existence that hasn’t really changed in over a decade and a chance to re-engage life. If anyone has experienced a similar scenario, is experiencing this currently, or has knowledge that may be of some use I would greatly appreciate it so I could pass it along to my folks. Thank you.
