The God is Not Willing by Steven Erikson

Many years have passed since three Teblor warriors brought carnage and chaos to the small lakeside settlement of Silver Lake. While the town has recovered, the legacy of that past horror remains, even if the Teblor tribes of the north no longer venture into the southlands. One of those three, Karsa Orlong, is now deemed to be a god, albeit an indifferent one. In truth, many new cults and religions have emerged across the Malazan world, including those who worship Coltaine, the Black-Winged God, and – popular among the Empire’s soldiery – followers of the cult of Iskar Jarak, Guardian of the Dead.

A legion of Malazan marines is on the march towards Silver Lake. responding to intelligence that indicates the tribes beyond the border are stirring. The marines aren’t quite sure what they’re going to be facing but, while the Malazan military has evolved and these are not the marines of old, one thing hasn’t changed: they’ll handle whatever comes at them. Or die trying

Meanwhile, in the high mountains, where dwell the tribes of the Teblor, a new warleader has risen. Scarred by the deeds of Karsa Orlong, he intends to confront his god, even if he has to cut a bloody path through the Malazan Empire to do it. Higher in the mountains, a new threat has emerged, and now the Teblor are running out of time.
The long feared invasion is about to begin. And this time it won’t be three simple warriors. This time thousands are poised to flood the lands of the south. And in their way, a single legion of Malazan marines . . .

It seems the past is about to revisit Silver Lake, and that is never a good thing . . .
