Firstly, my invite was for you to explain why all the memoirs listed were wrong. Cherrypicking one title out of 153 clearly doesn't meet that standard.
Secondly, quoting from a publisher's blurb doesn't demonstrate that a memoir is wrong. To do that, you would actually have to read the thing, and grasp the historical context, and explain to us what genuinely violates the historical record in Buergenthal's account.
That would require knowing things like the Nazis lowered what they considered to be working age in 1944, because of the labour shortage, allowing a small number of 10+ year olds to pretend to be older and thus slip through the system. In 1944, the Nazis explicitly stated the working age in occupied Belorussia to be 10. In the camps, it went down to 12-14 in the same year.
It would also require knowing that in some ghettos, the Nazis tolerated the survival of small groups of children for a variety of reasons depending on the locality, sometimes because the children were relatively well hidden, sometimes because the local Nazis were less bloodthirsty than others, sometimes because a compromise was made to spare family members of skilled workers but not unskilled workers, and so on.
Finally, it would help if you could explain to us the logic of your apparent claim where the survival of one person refutes the death of another. I've never had a coherent explanation from a denier why that follows logically at all.
