The Scholar, the Sphinx, and the Threads of Fate - A. R. Cook - Bog

The fight to save the world is just beginning.
Waking on the outskirts of Le Havre, David has no memory of his past or who he's left behind. Nyx has erased his existence, but there is hope: face the mysterious Moirai, the weavers of the Curtain, and have a new fate woven.
With old enemies on his trail and no one in the human world able to see or hear him, he must traverse the places and people of the past to regain his memories before everything falls under Nyx's shadow.
