Ever find yourself thinking, "What's it like to be the ex-wife of a hedge fund manager?" Well, wonder no more. Upper East Side mom and author Jill Kargman, with the help of Frederic Fekkai Fifth, launched her newest work of fiction, The Ex-Mrs. Hedgefund (self-explanatory) last night, and we're sure some hedge fund managers were at the signing.
