Sarah (The Canaan Trilogy #1)
Marek Halter

Many years later, Abram returns to Ur and discovers that the lost, rebellious girl from the marsh has been transformed into a splendid woman--the high priestess of the goddess Ishtar. But Sarah gives up her exalted life to join Abram's tribe and follow the one true God, an invisible deity who speaks only to Abram. It is then that her journey truly begins.
From the great ziggurat of Ishtar to the fertile valleys of Canaan to the bedchamber of the mighty Pharaoh himself, Sarah's story reveals an ancient world full of beauty, intrigue, and miracles.
