Efrat Ungar was born on October 17, 1971in Jerusalem to Uri and Yehudit Dasberg. Efi grew up and studied in Allon Shvut in Gush Etzion. She also attended the Zviah Ulpana in Jerusalem.
She served in the National Service as an assistant in the children's home in Afula. Following her service she studied graphic design and teaching at Emunah College in Jerusalem.
On September 13, 1993 (the day the Oslo Agreement was signed) Efrat married Yaron Ungar . The couple moved to Kiryat Arba where their two children (Dvir and Yishai) were born. Efi worked at the local community center as a graphic artist, illustrating the center’s various publications. For five years Efi worked as an illustrator and graphic designer in the children's section of the Israeli newspaper "HaTzofe", in which she regularly published a comics series.
On June 9, 1996 Efrat and Yaron were returning from a friend's wedding when they were murdered in a Hamas drive-by shooting near Beth Shemesh. They were buried side by side in the Kfar Etzion cemetery.
In the site of the attack, a monument was erected, with the assistance of the Jewish National Fund, in memory of Efrat and Yaron Unger. Later on, a scholarship fund was established at Bar-Ilan University in their names and in their memory.
After her death, her family published her series of books:
- Dvir (דביר) – the book was written after the birth of her son, and called his name. It was initially published entirely, while she was still alive, in the "HaTzofe" newspaper.
- Dr. Tetanus (דוקטור טטנוס)
- Waiting for the Messiah (מחכים למשיח)
- Ran HaRachfan (רן הרחפן)
- Mouse Beware (עכבר היזהרה) – a short comic stories.
In addition, Efrat's father Rabbi Uri Dasberg published the Book of Ruth with illustrations made by Efrat.
