Hagar Yanai

Yanai's third book, The Leviathan of Babylon, is the first of a fantasy trilogy. She wrote the book in a groundbreaking effort to create a widespread audience in the Israeli literary scene for the fantasy genre - her favorite. The book follows the adventures of Jonathan Margolis and his sister Ella, who enter a parallel world, the Empire of Babylon, ruled by the Guild of Hashdarpans – brutal physician-priests who fear the rise of the Leviathan, son of the Abyss. The book draws inspiration from Jewish, Babylonian and Middle-Eastern mythology. The Leviathan of Babylon was awarded the 2007 Geffen Award for Best Original Hebrew Fantasy.

Yanai's fourth book and the second in The Leviathan of Babylon trilogy, The Water Between the Worlds, was published in February 2008. It describes the beginning of the great battle for the Empire of Babylon. The four protagonists from the first book, Jonathan and Ella Margolis, Hillel Ben-Shahar, and Princess Nin-Urmuz, are faced with even more difficult challenges and ordeals. The Water Betwixt the Worlds was awarded the 2008 Geffen Award for Best Original Hebrew Fantasy. Yanai was also awarded the 2008 Prime Minister's Award for Hebrew Literary Works.

Yanai's second book, Alex's Eternity Machine, describes the journey of a rebellious female soldier in the Golan Heights. The soldier, Duba, runs away from a young and aggressive officer who wants to rehabilitate her, and looks for Alex, a young physics genius, with whom she fell in love in her youth, and who is trying to invent the Perpetuum Mobile. The book was nominated for the 2006 Sapir Prize for Literature.
