This is book number 1 in the Barsk series.
On the world of Barsk, uplifted elephants are isolated away from all other uplifted species in the galaxy–with the exception of the koph trade, a unique substance only found on the glum planet that the elephants call home. The residents of Barsk hold a tight monopoly on their main export, which grants its users the ability to Speak to the dead. When Fants start to disappear on their way to the final resting place, as foretold by the first Speaker hundreds of years ago, it’s up to Jorl — a historian, Speaker, and one of the few Fants to have ventured past the homeworld —to discover their fates, and ultimately to decide the fate of his people. A compelling story, rich universe, and characters that, despite appearances, are surprisingly human make for an immensely enjoyable read.— Darcy
The Sixth Sense meets Planet of the Apes in a moving science fiction novel set so far in the future, humanity is gone and forgotten in Lawrence M. Schoen's Barsk: The Elephants' Graveyard
An historian who speaks with the dead is ensnared by the past. A child who feels no pain and who should not exist sees the future. Between them are truths that will shake worlds.
In a distant future, no remnants of human beings remain, but their successors thrive throughout the galaxy. These are the offspring of humanity's genius-animals uplifted into walking, talking, sentient beings. The Fant are one such species: anthropomorphic elephants ostracized by other races, and long ago exiled to the rainy ghetto world of Barsk. There, they develop medicines upon which all species now depend. The most coveted of these drugs is koph, which allows a small number of users to interact with the recently deceased and learn their secrets.
To break the Fant's control of koph, an offworld shadow group attempts to force the Fant to surrender their knowledge. Jorl, a Fant Speaker with the dead, is compelled to question his deceased best friend, who years ago mysteriously committed suicide. In so doing, Jorl unearths a secret the powers that be would prefer to keep buried forever. Meanwhile, his dead friend's son, a physically challenged young Fant named Pizlo, is driven by disturbing visions to take his first unsteady steps toward an uncertain future.
