I forget who recommended this series to me, but so far it's pretty great.
It's about a captain and his crew of military sanctioned"mercenaries" on a secret mission to secure resources, establish diplomatic relations and kick ass all across the galaxy in the name of his independent homeworld. It smells a bit like Star Trek with a rogueish element, if that makes any sense. The first trilogy, Broadcast 0: Origins, is free on Amazon. Go grab it!
