Black Fridays — Michael Sears

Jason Stafford is a former Wall Street hotshot who made some bad moves, paid for it with two years in prison, and now is trying to put his life back together. An investment firm asks him to look into possible problems left by a junior trader who recently died in an accident, and Stafford finds problems, all right -- the kind that get you killed -- but that's not his only concern.

He has another quest as well: to reclaim his five-year-old son, "the Kid," from his unstable ex-wife, and then learn just what it means to make a life with him. The things Stafford discovers about himself in the process are every bit as gripping as his investigation, and when the two threads of his life come together, the results are unforgettable.
