Hagar has written two books.
The first book she published was Land Of Promises, which can be read or purchased at Rakuten Kobo and Apple Books. It's about Hagar’s growing up in Israel, her experiences and the experiences of others with parents that are traumatised and do their children harm. It goes on to extrapolate this to the Israeli culture and the colonisation of Palestine.
Land of Promises can also be read chapter by chapter on Substack. The second book is In the Footsteps of Anna Maria Cornelia Grader, which is being published on Substack, one chapter at a time. The first chapter is here

Hagar has created NFTs, more on these will come soon.
