If you've read any of the other books, it's pretty much like them, but more recent. If you haven't, you have some serious catching up to do. I think this is book number 87 in the collection about the adventures of David Thorne, the beautiful princess from Australia that moved to the US in the pursuit of happiness, snow and cheaper cigarettes.
Also, some heavy gambling happened at some point, but that is for another book.
#87 is the rarest number on the roulette, so it's pretty special, I guess. Which is also explained in the book.
