I just read the first in this trilogy, but can't find the other two.  One brother is a billionaire, one is a football player and the other is in the army. 

I should have found out if all three were written before reading the first.  Were they ever written? Anyone know?

Nope...the next two were never published and it's doubtful they ever will be.  There's a lot of negative discussion about this on amazon.  

From what I've heard though, haven't read it yet, the first one is really good.
