Peter David and John Ringo have a similar sense of humor to mine ... or I developed my sense of humor by reading them, pick one. I find Ringo inspiring, and David usually entertaining, when he's not putting his politics into it.
Timothy Zahn is "only" an amazing author, and most likely responsible for resurrecting Star Wars as a franchise (sadly, the book franchise might be the only reason Lucas felt comfortable trying the prequel trilogy. Bonus: Zahn has gone everywhere that Lucas has, and has outperformed the little sot.)
And John Ringo ... well, he's ex-82nd airborne, and legions of his fans are military vets. I really hope he doesn't mind. And that he likes the book.
