Thus Spoke the Dragon (The League of Planets Adventure Book 2)

Major John Gresham thought the Forbidden Army's trail had gone completely cold, but a new lead has emerged. Marsa Grakko, the krokator in charge of their dark money network, has been sighted at an abandoned outpost in the backwater of human space. But Gresham's erstwhile partner, Imperial soldier Akgu Zurra, has a bloody history with Grakko that could derail their mission.

Meanwhile, in the Briling Dominion, semi-retired Shadow Ops commando Riyao Seryin has been dispatched to Mirra, a remote colony that has been invaded by a pirate force. His small team has to determine the scope of the occupation and prepare for Dominion reinforcements to retake the planet -- but the invasion force is anything but ordinary.

Both missions are entangled with a common enemy. A cult-like mercenary army called the Crimson Dragons, with seemingly endless financial resources, has stepped up its activities to advance their only goal: the violent and complete overthrow of the established galactic order.

Thus Spoke the Dragon is the second book of The League of Planets Adventure
