Helsreach still, because Emperor beware I fuckin' finish it first before jumping into others...
In the wake of the Dropsite Massacre at Isstvan V, the survivors of the Salamanders Legion searched long and hard for their fallen primarch, but to no avail. Little did they know that while Vulkan might have wished himself dead, he lives still. As the war continues without him, all eyes turn to Ultramar and Guilliman’s new empire there, and Vulkan’s sons are drawn into an insidious plot to end the Heresy by the most underhand means imaginable.
In the depths of Calth’s arcology network, the Underworld War has raged for years. Aeonid Thiel, previously an honoured sergeant of the Ultramarines, once again finds himself in trouble – pitted against the daemonic forces of the Word Bearers, he has no choice but to venture back to the ravaged surface and brave the deadly solar flares that have scoured all life from this world. With a lowly Imperial Army trooper as his only companion, it falls to him to drive the maniacal Dark Apostle Kurtha Sedd and his warband from the overrun XIII Legion stronghold.
Thiel was a pretty cool character in Know No Fear, so I've got to listen to this new audio drama today. They just released it early via their website, with the CD version still a few months out.
