You are a whiz at sniffing out new books but beforre you go and whet everyone’s appetite, you should at the very least tell us where to get the book. I searched all of the regular haunts in the holy city for the book and none of them had even heard of it. Schar halicha I got, but alas no book. The sadness is overwhelming.
I only know of its existence through it being cataloged at the JNUL. Maybe give Yeshivat Hazon Ovadiah a call and see if they have it. It used to be in Romema behind the old central bus station among all of the car repair shops. I think that we maybe even went there once together.
