What to read after Navigator?

As the fearsome war between Christianity and Islam leaves its mark across the land, a rogue Spanish priest dreams of the final defeat of Islam, for he has found a rent in the tapestry of time, a point where agents from the future used diabolical weapons of destruction to change history. Centuries later, in 1492, as men of vision weary of the strife and are drawn to the unknown West, one such explorer seeks the funding for his voyage--while a mysterious Weaver plots to unravel the strands of time and stop him.--From publisher description.
