Much like its predecessor, this book manages to have no plot. It doesn't even attempt to end with a meaningful moment or a take away. Things just happen until you get to the last page, and then it's over. Especially humorous are the attempts at foreshadowing, as if perhaps a plot will begin to develop. At one point one of our lead characters remarks that he thought he would never see someone again and that later he would wish that to be true... and then it doesn't matter. Literally nothing that happens matters.
I suspect that Robbins identifies too strongly with his protagonists to actually put them through any kind of hardship. Someone's wife leaves them, will they be inconsolable? Eh, it'll be fine, they'll just marry a younger, hotter woman. A business partner is murdered, will that destroy the company? Nah, it'll just be an opportunity to get closer to their benefactor (who is richest man in the whole wide world!). Someone's girlfriend is secretly plotting to murder them, will they overcome this perilous plot? No problem, they'll just murder the girlfriend and her secret lover and it'll never come up again. Life just flows by, nothing sticks to anyone, nobody stresses anything, and everyone becomes fabulously wealthy but is never fully satisfied with it (but the lack of satisfaction is never reflected upon and isn't really a theme or anything).
Frequently, I read trash and feel like I've managed to extract a little interesting tidbit from margins either about the circumstances of its creation or the audience that it was originally enjoyed by. This book gave me no such glimpse of interest.
