Emanuel (Manu) Rosen is a best­selling author whose books have been trans­lat­ed into thir­teen lan­guages. He was born in Israel where he went to school, served in the army, and was an award-win­ning copy­writer. After his grad­u­ate edu­ca­tion in the U.S. and a suc­cess­ful career as an exec­u­tive in Sil­i­con Val­ley, Emanuel turned to write. This is his fourth book.
