I published four books to this day: three in Hebrew and one in English.
The first one, published in 2005, is a guide to the creatures the fill the worlds of legends
The second one is a guide to the iPhone, and it was published in 2009
The Third one was created specifically for the iPad; it's a children's book available both in English and Hebrew
The fourth is a guide to the web, commissioned by OPUS publishing
A fifth book for YA is in the works.
