A book written with Kahui twins' mother Macsyna King, which has yet to be released, has caused a public outcry, resulting in some retailers refusing to sell the book.
The twins' father Chris Kahui was accused and acquitted of inflicting fatal injuries on the twins in 2008. His legal team contended Ms King was responsible for the deaths.
The book Breaking
Silence: The Kahui Case
details Ms King's version of what happened.
