It has been a while but I remember Hyperion by Dan Simmons as a great audiobook. There is a lot of thriller, myth, and good storytelling.
Here is some synopsis:
Hyperion: On the world called Hyperion, beyond the law of the Hegemony of Man, there waits the creature called the Shrike. There are those who worship it. There are those who fear it. And there are those who have vowed to destroy it. In the Valley of the Time Tombs, where huge, brooding structures move backward through time, the Shrike waits for them all. On the eve of Armageddon, with the entire galaxy at war, seven pilgrims set forth on a final voyage to Hyperion seeking the answers to the unsolved riddles of their lives. Each carries a desperate hope—and a terrible secret. And one may hold the fate of humanity in his hands.
A stunning tour de force filled with transcendent awe and wonder, Hyperion is a masterwork of science fiction that resonates with excitement and invention, the first volume in a remarkable new science fiction epic by the multiple-award-winning author of The Hollow Man.
The Fall of Hyperion: In the stunning continuation of the epic adventure begun in Hyperion, Simmons returns us to a far future resplendent with drama and invention. On the world of Hyperion, the mysterious Time Tombs are opening. And the secrets they contain mean that nothing–nothing anywhere in the universe–will ever be the same.
